Nero/DVDLab Problem

[Nightcrawler]

I use a DVD Recorder to make copies of some VHS tapes. I then use DVD Decrypter to combine the .vob files onto my HD. From their I use DVDLab to author the video. The problem comes in when I get an error messgae from Nero 6 stating "File Re-Allocation Failure" . What could be causing this ? It doesn't happen all the time, but when it does it's extremely frustrating. Thanks.

instead of using dvdlab to join your vob files,which i thing the problem is,i feel you should rip the dvd into one vob file using dvd smart ripper(freeware).i'm not sure dvd decrypter does this.

I use DVD Decrypter to combine all the .VOB's into 1 file
