Hi folks, it's been a while but i'm back again!!!!!!

i've dl'd a fair few copies of lost series 2, which im burning to disc.

i'm using nero 6 to burn. the problem is, only the mpeg format burns fine, avi's etc dont and end up with the audio so far out of sync its unwatchable. but saying that, i've only tried to burn the mpegs once....may try a second burn to confirm that.

what i cant understand is why these files play fine on the pc????

ive converted the non mpeg files into mpegs (and dvd and a few others) without any joy. also, i thought it may have been corrupted torrents, so i dl'd an alternate but i get the same result when trying to burn.

please help....the wifes desparate to see these and im getting a hard time from her.

thanks folks

Two causes, something chewing up CPU cycles when burning, or, more likely, it is something to do with the AVis themselves. I have recently come across some AVIs that burn like you have found. I have found the only solution is to find another (different) AVI file.

Converting from AVI to another format may work as it has helped me with some problematic files in the past, but not with this problem though.

I used to get this with AVI files that had badly encoded VBR MP3 audio tracks.

The solution is to feed the AVI through VirtualDub and re-encode the audio track to a CBR 192KB/s MP3 track (use a very high MP3 rate as your going to get rid of the file later and you dont want any quality loss) and then feed that into your AVI to DVD program.

Setup the video stream to do a direct copy (Default is to re-encode) and the audio stream to re-encode (default is to do a direct copy). This should be relativly quick.

Thanks for that tip.

thanks folks,

i'll try that and let you know how i get on.

right, ive installed virtualdub and added one of the dodgy files, this is the message i get

VIRTUALDUB HAS DETECTED AN IMPROPER VBR AUDIO ENCODING IN THE AVI SOURCE AND WILL REWRITE THE AUDIO HEADER WITH STANDARD CBR VALUES DURING PROCESSING FOR BETTER COMPATIBILITY. THIS MAY INTRODUCE UP TO 16234MS OF SKEW FROM THE VIDEO STREAM. IF THIS IS UNACCEPTABLE, DECOMPRESS THE *ENTIRE*AUDIO STREAM TO AN UMCOMPRESSED WAV FILE AND RECOMPRESS WITH A CONSTANT BITRATE ENCODER. (BITRATE: 124.2 +- 13.9KBPS)

does that make any sense to you folks?? and one last thing.....where will i find a user guide for this, the virtualdub site doesnt have one and im not too sure what im doing. i will persevere for as long as i can.

any help will be appreciated.

thanks

Yes that does make sence, that is exactly what you out of sync problem is

Ok, click NO at that point as you dont want to re-write the header (will mess it up even more)

The in Virtual Dub you can click on Video and make sure Direct Stream Copy is selected (not the default), then choose audio and select full processing mode then choose audio again and choose compression. This will open up all the audio codecs available on your system. Choose LAME MP3 (I presume you have the Lame codec installed, if not google for it & install it). Choose the either 44100Hz, 192kbps CBR Stereo, then click ok.

Now save the file with a new file name. It will take a few minutes as it is re-encoding the audio to a CBR format. Its quicker than a full re-encode as it is not touching the video at all.

If this does not fix your sync problems then you may have to strip the audio track out of the AVI file, convert it to a WAV file & then re-combine. Best thing for this is to look on the www.doom9.org forums for more info, or even try www.divx.com forums as well.

thanks for all your help.

last question (hopefully)

when i save, which save do i use?????

save as avi
save old format avi
save segmented avi
save striped avi
save striped master
save image sequence
save wav

cheers

im back...

ive saved as avi - taking about 8 mins to finish.

i used the settings you recommended 41000 @192kbps cbr stereo and it wouldnt accept so i used 48000 @ 192 so on and so far so good...........

Yep, correct. The source audio was obviously in 48KHz (48000) so yes you did the correct thing.

Hope it works for you as going the VBR MP3 > Wav > CBR MP3 can get quite a handfull.

all my love to qwakrz......you are the man

yes it worked.

thank you very much for your time and patience with this.

i just hope all i learn in here i can pass on to others some day.

again, thank you.

the lost file is recorded from tv, then added to pc and converted. in their wisdom, the uploader cut out the adverts. is this the cause of the sound going out of sync during the burn??????

again thank you....im the wifes best friend and who knows how shell thank me

Hello

I have the same exact problem as mentioned in the beginning of this post. I have some TV shows I want to burn, but I'm always getting audio sync problems. I have Nero 7. The audio goes out of sync when I burn the DVD through Nero Vision express when it's played back on the DVD Player. I"ved tried the suggestion from Qwakrz using VirtualDub to re-encode the audio to CBR. Then reburnt the new avi but that still didn't work. I've tried Divfix to make corrections in the file but it found none. I was thinking of re-encoding to divx using DrDivx before I burn but I doubt that will work either. From everything I've been reading Xvid and VBR is the problem for those who wish to burn to DVD. The file is 100% perfect if viewed on the computer, but try burning some. It's strange I have dozens of xvids', some burn ok and alot don't. The only real solution I've found is to strip the audio track to MP3, strip the video to mp?, then use a third step to re-encode the video and audio back together to fix the problem. I'm guessing there is no easy single app to do this. Could someone point me to a dummies guide to correcting these problems the longhand way since there doesn't seem to be an easy way. I"m looking for a step by step solution to this problem. From what I'm getting each video is different in it's audio sync problem and only manual manipulation will correct it. I read somewhere the video file may need to be split in to 4-5 parts and the audio adjusted in each part for bad audio sync problems. I'm a video newbie thats want to learn. But right now I just want to watch TV shows I"ve downloaded on my DVD player. I thought Nero 7 would be the end all to my problems but these pesky Xvids are a pain. Could someone please list some options.

Thank you

The only thing you can do if a quick re-encode wont work is to strip the audio out of the file as a WAV file, re-encode it back into a higher bitrate MP3 and then re-join the file back together again.

Virtual dub will do it all for you but you have to tell it what to do, load the file & save the WAV file (look under file menu), then on the audio stream choose WAV file as source and point it at the wave file you saved, and proceed as I wrote above on re-encoding it back to MP3.

Almost all my homemade XviD files have VBR audio tracks BUT I dont re-write the header (which most people do) and assemble the video by hand using nandub (modified virtualdub) so I dont get the sync error.

I would be careful when discussing illegal TV-Rips, even more so for shows that are on DVD.

Okay guys and gals, I first off want to thank everyone for trying to fix this issue. But after litterally spending two days messing around with all the various suggestions mentioned, losing about 15 DVD's to out of sync video, I decided that I needed to fix this before I went nuts.
After reviewing all of the info and trying many of the suggestions, it came to me that I did not start having this problem until after I installed the latest and greatest copy of Nero Vision Express 3.1.0.7 on their web site over a week ago.
I am unsure what the reason for the audio sync problem is, but I do know now that Nero is solely to blame for it, and not my PC or the files I got from my TIVO box.
In reading here and on other forums the various solutions, I found out, all though I was not sure, that this issue may be resolved by reverting back to a previous version of Nero Vision express. In the US, I had no luck locating anything older than 3.1.0.21, but after some extensive research, I found an earlier copy "NVE-3.1.0.14.exe" on a Korean site, here is the link:
http://download.zdnet.co.kr/pds/deta....html?id=19110.
No I do not speak Korean, but by looking at the page, you can tell what the intent is. You click on the big"button looking" thing, which takes you to another page with a similar button. Click on that button, and your download begins.
Uninstall anything and everything that has to do with the latest and greatest copy of Nero Burning Rom, and Nero Vision Express.
I used the original software of Nero that came with my DVD/CD burner and this included Nero Vision Express 2.1.0.8. I installed over this the later version NVE-3.1.0.14.exe, and voila, the problem went away.
In short, the problem is definitely with Nero Vision Express, the suggestions given using Virtual Dub, DivX etc. did not work for me, but I am happy to say, I can continuing backing up my TIVO files to DVD.
Oh, in case the question arises. I added three approx. 45 minute TV shows of CSI as a test (they failed miserably before), and tried them on two different DVD players. They both played perfect all the way through, and it was very clear the problem was fixed, as the files were the same, but the audio sync problem was no longer there which normally started right after the first commercial break.
Thanks again for everyones help, and as I felt compelled to let you know my own struggles, and the fact that I used all suggestions, I hope this fix makes your life easier, I know it did mine.
Peace!

PS. I do not promote the illegal copying of DVD's, but feel very strongly that I have the right to backup my copied TV files like I did for years with my VCR.

Enjoy!

try using VSO's divxtodvd program. I've never had a problem with out of sync issues using this but when I used Nero Vision Express or Avi2Dvd i did run into sync problems often.

I cannot lay this issue at NVE's door in my case. I'm using v3.1.0.11 and the out of synch issue is only related to releases for a certain sci-fi program. Other video files are okay.

I found the videodub trick did not work on its own, I have to convert the AVI to a dixv AVI first. Possibly just the conversion may have helped on its own. May do some testing when time allows.

after 3 days and trying everything to solve the audio sync problem i have finally done it with PERFECT RESULTS.

i tried everything, older versions of Nero, VirtualDub etc etc etc.


tehn i saw another posters suggestion and put it to the test.

IT WORKED!!!

this works for Nero 6 vision express all versions.

DISABLE THE Nero CODECS

its that simple, once this is done you will be able to make dvd's from avi's without the sync problem.

how do you do this.

1.remove your digital serial number. (make sure you keep it somewhere to re enter later)

2. put your pc's date forward 1 month so the codecs expire.

3. use Nero vision express, it will now work correctly.

when done, put your serial number back to you can use recode and other things that are disabled when you remove the serial. also dont forget to put the clock back to the correct date.

Hey all,
I stumbled upon this post and am having the same issue.
I tried to do what qwakrz says, but Virtualdub wont recognize the AVI's compressed audio.
I ran Gspot on the file and it told me that the Audio format was:
48000Hz 128 kb/s total (2 chnls) LAME3.95 VBR

I installed the LAME Codec Ver 3.96.1

When I try to save the AVI file, it says there is not a suitable codec installed to decompress the audio....

Any idea why that might be happening??
thx
Southpaw

southpaw, just follow my instructions on how to adjust nero and you wont need to use virtualdub

southpaw follow my instruction and it fixes nero

Just curious, has anyone tried Kekes solution? If so, could someone please explain when exactly you put the serial number back in? The Nero program will not work (for me anyway) without a serial number. After removing the number and changing the date and then trying to use the program, it asks for a valid serial number before the program will let you access it. Before proceeding I wanted to know if this is what is suppose to happen. Any input would be appreciated.

ok..I found the answer...
http://forums.virtualdub.org/index.p...dc04f58861bd92 ... &st=15

Turns out the AVI was not being recognized correctly by the Frauhoffer codec.
I used the hex editor to adjust the file and voila!
Nero 7 NVE works great

thx for the help

hey, it the digital plugin serial that you remove. not the actual nero serial for the program. in the serial section you should have the nero serial for the software plus any other serial for added plugins(that u may have installed). if you dont have the nero digital plugin then that step is not needed. just move the pc clock forward 2 months to be safe. then start visionexpress. when you load the avi nero should pop up saying that your mpeg 4 codecs have expired. this is what u want to occur. just click close on the pop up and continue. the sync should now work. dont forget to put your pc clock back afterwards. u will have to do this everytime until the actual codec expires (30 days).

Hey, I have the same problem as above using nero 7 (nerovision 4) but can not finf the way how to remove nero codecs in this version. Can somebody help me? Thanks
