sometimes DVDR - DVDR fails due to weird filesize problem ??

[Spiny Norman]

Anyone a clue on the following problem that's driving me nuts?

I have a DVD-R (converted from an old tape by someone else) that I can't copy.
The problem is the size. No matter how I copy the files to hdd (directly, dvdshrink, dvd extractor) the burning program will only enter them into the project as some 15-30 seconds. I tried Ulead and nero vision.
The copying seems to be alright because the filesize stays the same.

It all seems very illogical. I tried the same thing with normal DVD's ( region free, region 1 and 2 ) and I could copy all except one that had the same problem.

So, anyone a clue? Please?

Try DvdDecrypter to both copy and burn
Use Iso Mode->Read to rip Iso Mode->Write to burn.

Yes, it was the next thing for me to try, simply burning identical copies.
But in one case, I really need to select one fragment, for a new compilation.
That should be perfectly possible... right?
