I'm encoding AVI streams captured from a DV camera to DVD standard MPEG-2 using TMPGEnc 4.0 XPress. I'm finding that if I choose to create the MPEG as "SYSTEM" (Video + Audio) that when I author the DVD (Using TMPGEnc DVD Author 3) I get only 1 channel of Audio on DVD playback, in this case the left channel only. When I encode the MPEG as an elementary stream (mv2 file + wav file) I get sound on both channels on the final DVD. Why? It seems more convenient to encode it all to one file than to separate it into two separate files but I find the one channel sound annoying. That's the first question. Second question is: Should I encode the audio as PCM, MPEG-1, or Dolby Digital? I can see no clear recommendations on this. Third question: When I play the MPEGs encoded with both video and sound Windows Media player won't play the audio, while other media players will. Why would this be? Man do I hate fooling with video. Can't they simply make just make this stuff work? Any help would be appreciated.
