Nero SVCD Burning



I’m new at burning SVCD’s using Nero. I used DVDDecripter to make the DVD files useable. I then made SVCD’s (3) with the VOB files using Nero. Part way through the first disc, the audio stopped playing on the recorded discs. The second and third disc had no playable audio too. Anybody familiar with this problem?
