Hi... I have the above mencioned drive... I can burn the -R disks with no aparent write errors, but when i try to read the burned disk, everything seams fine, till reaching the end of the disk, where read errors start appearing, speacially in movies..

Used media: princo -R 4x / BULKpaq -R 4x (orange ones)
Used software: CloneDVD2 / Nero / Alcohol 120%

every combination of media / software brings me to the same problem...

Deffective drive???

Tks in advance...

do a scan using nero cd-dvd speed and post your results.
may be just baddd media you're playing with.

Don't use cheap media (Princo), try Maxell or Verbatim and see what a difference high quality media makes!!!

Try better media, if the problem persists its a defective device.

Better media could be: Verbatim, TY, Philips, TDK, ...

Avoid media like: Princo, Sky, SK, (Intenso), other cheap media, ...

Here we are... This is with Princo.. I've just read your replys. Going to buy some quality stuff tomorrow.. any way...

Buy +r or +rw. Cause the 822 likes + more than - .
But it should also burn quality - well. If not something is wrong.

For the record:
I tried burning Princo DVD-RW. The Burning failed and the disc is now unreadable.
Before that the disc was burned with a pioneer without problems.

Hi again... just bought some TDK 4x -R's... i'm burning one as we speak... will post results when finished.. Regards...

Ohhhhhhhhhhh Yeahhhhhhhhhhhhh

No doubt TDK shows the difference...

Now i'm pretty sure the drive is OK...

I LOVE MY BENQ

Well. Thats exactly how it should look like for a good burn (on a Benq822):
PIE: not over 50 for a longer time
PIE_Average: under 30
POF: 0!!!
Jitter: always or at least mostly under 15
Jitter-Average: under 15
QualityScore: over 90
(imho)

Bytheway: Your TDKs are from TTG a Sub-Brand from Tayo Yuden.
Means good stuff.

Keep in mind:
The Benq822 is not capable in the moment of reporting PIF. So they are not 0. They are just not reported. They should not be higher than 4.

My advice:
If you want quality-burns. Don't burn 8x. 4x will give much better quality.

TTG is NOT a TY sub-brand, they are CMC!
CMC DVD media is good quality though, so no worries there.

Tks guys... i'm a little lame yet on the dvd burning market

Hi... here I am once again... Bought some cheaper media than TDK, which I could get for half the price here ir Portugal... Something called.. Sony... (yes, half the price) and here are de results... I'd love to see your comments... Thanks..

try scanning on another drive @4x

The Sony/MCC media should burn and scan great. IIRC Verbatim is using the same MCC media and the scans are excellent.

Are you trying to go somewhere with your comment???

Hi ChAbReGas,

The BenQ drive scans very slowly - your graph above shows a speed of only 1.36X. It's a lot easier for a drive to read data at this slow speed, and perhaps not as representitive of quality as your above (excellent) scan might suggest. Hopefully, a future BenQ firmware upgrade will correct this limitation.

The folks in the LiteOn conference like to do all of their scans at 4X (mostly for consistency), hence the above comment. However, I personally prefer to scan at the full 8X or faster, since a marginal burn will really show up problems at these higher reading speeds.

Anyway, if you have access to another DVD drive, it might be interesting to see just how well it does when scanned at a higher speed.

thanks for clearing that up Spartane

I don't think it dose matter that.
Even scanning by low speed, Benq's drive has its own standards for defining a good disc or not.
You can establish the norms by your own drive.
What PI/PO scan can be for sure is that it's always better to compare the data by the same drive.

what good is it if the drive you burnt the dvd is the only drive that can read it properly?

>like to do all of their scans at 4X (mostly for consistency),
consistency is not the main point there, 4x is a good speed to scan

>I personally prefer to scan at the full 8X or faster,

Simply not true that easy. urban legend. Read all the threads about highspeedscanning..

>It's a lot easier for a drive to read data at this slow speed
AFAIK benq limited scanning-speed to 1x simply because they believe that this is the most useful scanning speed, and not to betray with the results.

>Hopefully, a future BenQ firmware upgrade will correct this limitation.
if they do, than hopefully not higher than 4x! more important would be POE-Scanning. But I think this is a limitation of the used Philips-chipset...

>what good is it if the drive you burnt the dvd is the only drive that can read it properly?
thats right therefore it's always a good idea to scan a media in different drives. But if you have only one, using this one for scanning will give you a good idea already...

>Anyway, if you have access to another DVD drive, it might be interesting to see just how well it does when scanned at a higher speed.
Partly agreed: it's always a good idea to scan a media in several drives. Highspeed-scanning can give consistant results or can give weird results. Weird results do not mean something is wrong with the disc. Try scanning at a different speed (lower or higher) in such cases.

for example?

A few examples:

1. Many people burn DVD movies to play on their TV players. The player must be able to read them.
2. Some people burn discs to share with their friends. It's a bit embarassing when a friend complains to you that he can't read your discs.
3. Your burner might some day die and be replaced with another drive. It would be bad if it couldn't read all your old discs.

What you mention above has anything to do with high speed scan or low speed scan?

Good high speed scan result doesn't guarantee full compatibility.Neither does it get you nice readability on other machine.

So I don't get your point.

should have quoted your entire statement my mistake but here you go.
if benq has its own standards for defining whats good or not what is to say that other players will meet their standards.

If you try to estabish the norm by your own drive it will only be the norm for that drive and not others.

just because your dvd-writer will play your dvd or scan it well, it does not mean that other dvd-players or dvd-drives will read it just as good.

Playback well in DVD player may be good under Lite-on DVD Rewriter by PI under 280(sum=8) on Kprobe.

When it comes to benq with CD Speed Quality test, the same disc may be by the number around 200(hypothesis here). So you can establish your own norm to judge good or bad disc.

Basically, PI/PO is not concern with compatibility. As a foundamental premise, PI/PO is JUST showing the read errors on THIS DRIVE. So taking a high speed scan on other drive with good score means what? It still can not generalize to other DVD player.

Return to the head, higher speed without fixing at constant make the whole disc under an unfair condition to be determined. At the outer sectors with a higher PI/PO, how can you rule out if its reason is too high speed or just its bad quality?

If you really want to check the disc performance on CERTAIN drive or DVD-Player, you should make a practical test, not by PI/PO.

BTW, English is not my native language. If there is any misunderstanding statement in my posts, I apologize that in advance.
