I want to copy my German Iceage DVD which movie is already smaller than what fits on a DVD-R. This is what it looks like:

---
Movie 1:17:55
AC3 6ch English

AC3 2ch English Director comment

Normally DVD2One should not do any transcoding of the movie if it already fits on the DVD-R without it. So I looked at the result and compared it to the original DVD.

I also used DVDShrink to rip the DVD and got the following results:

Notice two things:

1) Both, DVDShrink and DVD2One killed the menu (as I chose to), but DVDShrink does it by fixing the VOB-IDs whereas DVD2One creates an "empty" Vob-ID 1 as a replacement for the original menu. Is any of the two methods "preferable"?

2) More important: On the original DVD, the main video has 2594.87MB, whereas the DVD2One video only has 2593.74MB. Why is that? Notice too that DVDShrink is identical to the original movie video size (minus 1 MB). Explanations?

Thanks in advance

If the move is less than 4.31gb,why dont you simply rip with DVDdecryptor and burn it to dvd-r ????

OR,if you hate menus, you could just rip the main movie with DVDdecryptor and then let dvd2one create new ifos.

OR, you could change the pre command with ifoedit to "jump to title".

But i suggest not wasting your time,just rip,burn and enjoy.

Maybe I wasn't clear enough. The entire DVD is >4.3Gb (around 7 or so) including menu and extras. I usually only want the movie, and that one alone is <4.3Gb. So I ripped the main movie only with DVDdecryptor. And, as you suggested, I then let dvd2one do the new ifos. And above you see my findings.

DVD2One creates movie vobs which size are off from the original movie, despite the fact that there was nothing to be transcoded. DVDShrink, on the other hand, produces the identical movie vob files.

And there was the thing about how DVD2One creates a dummy menu, whereas DVDShrink fixes the Vob Ids. I don't know which of the two is "better".

Hi,

The best thing to do is use DVDdecryptor. Select mode, ISO, then read. In the white box is a lot of data, beside the word Layes is a number (1 or 2). If it's 1 use DVDdecryptor to make a 1:1 copy, no quality loss. If it's 2 use DVDdecryptor to rip the movie files and use DVD2One to make the DVD.

Mike

Thanks for your reply - but this is again not really what I was asking. Lemme try to make it easy

Question 1
Original DVD: Video packets : 1328575 = 2594.87MB
DVD2One: Video packets : 1327996 = 2593.74MB
DVDShrink: Video packets : 1328566 = 2594.86MB

My point: Despite there is nothing to transcode, DVD2One *does* something to the original movie stream as apparant by the difference in movie size (DVD2One is off by -579 packets). DVDShrink is off by +9 packets. And both programs claim that they leave the main movie untouched when it fits on the DVD. So what accounts for the size differences from the original DVD?

Question 2
Original DVD has two (2) VOB-Ids. VOB-ID 1 : Menu, VOB-ID 2 : Movie
DVD2One has two (2) VOB-Ids. VOB-ID 1 : empty (dummy) Menu, VOB-ID 2 : Movie
DVDShrink has one (1) VOB-ID. VOB-ID 1 : Movie.

While DVD2One creates a dummy menu of size 0 so that it can keep the original VOB-IDs, DVDShrink corrects the VOB-IDs when it deletes the menu. While both ways seem to work, DVDShrink seems to me "closer" to DVD Specs since I have never seen 0 byte VOB-IDs used by Original DVDs.

Hope I am clear THIS time. Sorry, English is not my mother language.

dvd2one is much better quality.

I think you are being clear, just no one is answering you.

I don't know the answer though.

I often do DVD-5 movies with DVD2ONE. I know that they can be ripped and burned with DVDdecrypter without loss of quality or content, but I prefer "movie only" rips and DVD2ONE is easier than using IFOedit ect to extract the main movie files.

What he's asking isn't for a way to do these things, he just wants to know why, given that both programs claim they don't re-encode anything is the selected movie will fit on a DVD-R unmodified, why would there be a difference in files sizes between the two.

It doesn't seem that big a deal to me - because the difference is so small, just thought the original poster might be getting annoyed by the people saying "just do this" to copy a DVD-5 instead of reading/answering his question.

It is not exactly the same.... In order to process through DVD2one you have to Decrypt the files there by removing encryption keys and user prohibitions. This is probably why the packets are different.

I am going to repost my question on doom9.org.

I am surprised that no DVD2One developer here felt it necessary to answer my questions. Oh well.

Andrew

Well i didn't answer cause i don't felt the need to add anything usefull to your statement.

I know for a fact that DVD2one does not compress movies who are shorter, but process them anyway. And that means every single byte runs thru our program and since it isn't a copy program who needs to make a byte exact copy some things are being changed.

For example of you remove a soundtrack, some stuff is shuffled throughout the files.

This thread explains how to do it on a Mac. I don't know if the programs are available on PC, or not. Sorry, if this doesn't help. Good luck.

It was more a question that a simple statement. In fact two questions.

Thanks. Makes sense.

I'd be very happy if you could also answer my second question. The part with the dummy menu and why DVD2One creates it instead of correctly fixing the VOB IDs. Dummy (empty) menu VOBs are not really part of the DVD specs.

Best Regards!

If you have the REAL DVD specs, feel free to share them. Because we couldn't afford the book'o specs so we reversed a lot of stuff.

But if you have the real specs, you know the very expenive ones which the DVDforum hands you over after transfering a large amount of money and sign the NDA.

As far as i know, DVD2one corrects some pointers and creates a dummy file, because some hardware players bounced the discs when the menu wasn't there.

thats true,even the discs i authored ,without a menu, using MyDvd and ULead video studio also include a videots file. the pre command is set to jump to title. it has to be there.

When I do a DVD Decrypter ISO read and burn, the subtitles default to "ON" all the time. It's annoying.

With DVD2ONE, I can remove the subtitles or turn it "OFF" using IFOedit before I burn.

If the DVD Decrypter ISO is a true copy, when why are the subtitles "ON" when in the original DVD they are "OFF"?

I have found the exact same problem but luckily I only have 2-3 backups with subtitles.

How is that possible, when every single DVD I own (I have bought and currently own over 500 DVD titles, all region 1) has english subtitles...
