I have an APEX AD-1500...my problem is that my audio becomes un-synched with the video, and the difference grows the further you get in the movie....I use TMPGEnc to convert my mpg's and divx files into VCD/SVCD format (I use the steps provided on this website) and the converted files play fine on my pc (no sync problems at all) b4 i burn them. but once burned, I start having audio sync problems. I don't have the problem on all of my cd's, but most of them exhibit this problem. Any suggestions would be greatly appreciated...
