I authored a DVD in Nerovision and when using the Nerovision preview, it played just fine.
Then I "burned" the DVD to a hard disk folder (my usual practice, so that I could preview it in WinDVD before actually burning it to a DVD-R).
The video starts out fine, but about 20 minutes into the video, the video skips ahead about two minutes while the audio plays perfectly. As a result, from that point on, the audio and video are out of sync by about two minutes.
I've never had this problem with Nerovision before. Does anyone know what caused it, or how to avoid it in the future?
