I recently bought ADS Tech DVD Xpress device to convert VHS tapes to DVDs. I started capturing a fairly long VHS tape (2.5 hrs). After capturing the video in MPEG2 format, I played it to check the audio sync. In the beginning the video looked ok, but as time goes by, I can see a 0.5 second audio delay. That is, picture runs first and then audio. ADS Tech boasts they have LIP SYNC technology but in my case it doesn't LIP SYNC. I am using a P4 2.53 Ghz, 1 GB RAM. I am capturing the video onto a new partition dedicated for video. I defragmented the hard disk and enabled DMA. Anyone please let me know what I should do to fix this problem. Thanks in advance.
