after encoding an avi to mpg2 using tmpgenc on play back in media player the audio stutters. i use virtualdub to take out the audio, and dependant on wether its ac3 or mp3 i decompress it to wav. the audio length is equivalent to video length and on their own each file plays without a problem, only after the encode does this jittering audio problem surface, please help for I may pull out all of my hair!
