You first need to seperate into two streams, Audio (MPA)or maybe(MP1) and video (MP2)or maybe(MPV).You could pick up a trial version of TMPGEnc to do this.. But I’ll bet it is an option in Encore. From there you need to convert the audio to Dolby (AC3), doable in some of Sonic’s, Adobe and Ulead’s programs for PC … Check Ebay …
