Hi, I have a video file I'm trying to encode but I keep getting an error in VirtualDubMod...........ACM reported error on audio decompress(200), now I've checked the source file and it plays well with the audio fully in sync. What happens in VirtualdubMod is towards the end of movie it reports the error and when I play it..........the new file from virtualdubMod, the audio goes out of sync.............first time this happens to me. I repeat the source file plays well and is in sync so why the error when I put it through virtualdubMod?????.............can anyone help please???..........VirtualdubMod settings for video are direct stream copy and for streams full processing mode.
