Is the -R/+R incompatibility causing my problem copying DVD?

[stevkaprel]

I borrowed my daughter's video DVD of her wedding in order to make copies for myself and others in the family.

When I tried to copy the disk to another disk or to my hard drive, it would progress to over 90% and then stall. (There was no error message. The busy light just stays on but there is no more progress no matter how long you wait.)

I then found that I could copy the files on the DVD individually, but one of them (a VOB file) continued to have the same unsuccessful effect.

I tried to copy the file using several downloaded applications suggested by others (DVD Decrypter, ISOBuster, AnyDVD, CDCheck, DVDFab Decrypter) but each had the same result.

One of these applications told me there were no recognized copyright protection schemes on the disk.

The DVD can be played on the DVD drive and on the DVD player connected to the TV. However, the final portion frequently hesitates on the computer.

One of the dowloaded applications tells me that the disk is a -R not a +R. I have a +R drive. I didn't think this could be the cause of the problem because eight of nine files were copied successfully. Am I right? Could the -R/+R situation be at fault? If so, can it be oversome?

No, it's not a -R/+R problem. Sounds like it's likely a problem with the vob file that won't copy. DVD players will often overlook or "skip over" some errors on a disk and continue playing (sometimes freezing for a few seconds while it trys to read the bad spot) before continuing play. When trying to copy the disk (or file) those same errors will stop the copy process because that part of the disk is unreadable.

If there's a another copy of the disk available you should try it. (And I've had situations where a different disk will have an error in a different place- in that case you copy all the good files from one disk, then copy the missing files off the 2nd disk into the same folder.

in your OTHER thread on this matter, I suggested something...did you try that?

In my experience this is usually due to a VOB file that's larger than roughly 3900 megs. Video files beyond about 3900 megs tend to be problematic in copying because when you get to the outermost sectors of a DVD-R or DVD+R recordable disc, the rotations speed is so high that the servos in the optical read head have a hard time adjusting.

I had such a problem just the other day when I DVD'd "The Colossus Of Rhodes" off Turner Classic Movies. At 2.5 hours, it clocked it at nearly 4200 megs and wouldn't copy properly.

What I did (which always fixes the problem) was simplyl to rip the VOB, demux it, and then run ReJig to compress the video from 4200 megs to 3600 megs. This modest 15% compression produces no visible artifacts with ReJig, let lets me re-author and susbequently copy the DVD without problems.

First, it's very, very rare to find a vob file larger than 1 Gb. I assume you mean the total of the sizes of all the files on the disk.

While it's true that DVDs tend to have problems closer to the edge of the disk, I think they're mostly caused because that's where the disk is most likely to start to separate. If there are problems because the drive can't read due to the rotational speed then it's likely you need a new drive.

I can't see how your solution is going to be of any use to stevkaprel. First you rip the vob(s?)- that's exactly what he can not do. And since he can't rip the vobs he can't compress with Rejig or anything else.

And if you can rip the vobs (ifos, bups) then there's really no need to compress- you can just burn a new disk from the ripped files without compressing anything.

From what was described, it seems that there is physical damage to the disc that error correction cannot compensate for. Try to get another copy of the disc. Also, another dvd drive may do better in reading the disc and making the copy.
