Unable to copyDVD

Trazibul · Post by **Trazibul** » Wed Jan 17, 2007 11:57 pm

Hello,
I can't copy home DVD edited and burnt with VS10 (trial version).
I get the message "access violation at address...in module vobscr.ax..."
This was fast and easy when it was burnt from VS7.
I use Instant CD/DVD to make several copies of holiday movies.
Is this a problem with the trial version of VS10 (it's out of date at this time)?
With VS7: I edit my movie, add titles, effects..., then make an MPEG2 file, and burn a DVD-RW; then I check on DVD player(s), if it's OK I make several copies for friends or family; and I hope they can themselves make copies of this DVD.
With VS10: exactly the same procedure, with the same machine but I can't copy the DVD-RW!
Any idea about this issue before I purchase VS10?

Salut,

Si vous pouvez lire le DVD sur votre Lecteur, c'est qu'il est conforme.
Voici possiblement un "WorkAround"

Pour vous depanner, vous pourriez copier son contenu tel quel sur sur votre disque rigide puis rebruler le tout en utilisant Nero ou un autre copieur.

Au pis aller, vous pourriez le rebruler avec VS 10 PLus en choisissant
Share -> Create Disk ->Import DVD Folder. Cela vous permettra de faire vos copies au moins sans toutefois regler les autres problemes.

@JustOneOfMany

in case you haven't noticed, this boards official language is english. If you think you can help a poster with a reply in their native language, fine, but for the benefit of the others, not understanding your post, you should provide the english translation as well.

Sorry,

Wanted to be helpful to the member and forgot to translate. No disrespect intended.

In short, I argued that because he could read the DVD on his reader it was done properly by his version.
He could then copy the content of his DVD (copy paste) to his hard drive and then burn that folder to a new DVD using Nero or whatever he has if version 10 is faulty.

Or he could use version 10 to burn again Share -> Create Disk ->Import DVD Folder if it is not faulty.

Acceptable workaround to burn the copies he wanted so badly.

No need to apologize. Just wanted to point out that not many of the usual participants here do speak/understand french.

No harm done.

The facts of the matter are: every disk you buy will have some errors, every burn you do will add some more. Because of the weaker signal level with RW disks, the problem is compounded.

It is not recommended to copy burned disks because of that. It's better to burn to DVD folders or an ISO image to your hard disk and then copy that to as many DVD's you want.

A properly authored DVD, AFAIK, cannot be copied by placing a copy of it on the HDD and then burn that to DVD again. The addressing of disk segments is different on the disk and on the HDD. That may be the reason for the problem you are having already. It would be very easy to copy any DVD if that worked. Simply burn the file structure to the HDD and then burn it back to another disk. The file allocation table structure is different between HDD and DVD disk. At least that is my understanding of it.

I agree with you heinz-oz that using that method is not recommended and should be avoided but in some cases that's the only method left.

To my experience (limited I may add, only three years of fiddling around in the video department) it turns out that with non commercial DVD's (no protection) it ususally works. I've dubbed a couple of my DVD's that way and they turned out perfectly and played on every player around.

That simple workaround saved me some frustrations a couple of times.

I still agree that it is a last resort move, that it is doable when the disk is ok and that nothing else seems to work. (Import DVD using VS etc...)

Cheers,

Pierre

Actually, if you can copy the files from the burned DVD back to your hard drive, you shouldn't have any problems. I often do that for clients who only have a DVD for the source (either previously authored, or dvd-camcorder, or dvd-recorder unit). It's more the order of how they get burned back to disc that is important.

But agreed, the best approach would be to make your originals to DVD Folders on your hard drive, and then burn from that...

George

Thanks for fast replies, even in French!
Heinz-oz, does it mean that VS10 has created a copy-protected disk? As JustOneofMany said, I thought there was no protection for non commercial DVDs?
I just wanted that DVDs I have sent to far friends (Vancouver...) could be easily dubbed; this was possible when I burned DVDs with VS7, no more with VS10.

No. It doesn't have anything to do with copy protection. Your original blank DVD disk already has errors on it. Then you go and burn your video to it. That will add more errors. If you then copy that DVD again, more errors are created and added to the original blank disk errors.

Set top DVD players have error correction facilities that may still let you play the disk. However, because there is no physical law behind it that makes it behave in the same way each and every time, you will not know that the inheritend errors are already on the limit because you DVD player still manages to play that disk due to the error corrections it can do.

VS doesn't have that luxury. If there are errors in the DVD files, VS will/can hang itself up on those.

Facit: If you cannot import the DVD files to VS, these files may be corrupted even though the play on a DVD player.

Have you tried a straight CopyDisk with NERO or another burning program?

Yes, that's exactly what I did with Pinnacle InstantCopy, and it worked fine when the "master" was burnt with VS7, not with VS10 trial!
I'll check it again after purchasing VS10, and I"ll try to make a direct copy on another PC, something may be wrong on my machine.
