im using TMPGEnc to convert an avi file to an MPEG file and when it finished, the movie played fine, but there was no sound. i got help and extracted the audio and saved it as a wav file and put that as my audio source and converted the file, but still no sound when i play back the new MPEG file on my computed or my DVD player. ive looked everywhere but nobody seems to know what to do. can anybody help me?!
