I posted this to another forum, then found this forum. Here is the issue:

I am having problems with the audio being out of sync with the video on .divx converted files. Files downloaded from the Divx website (Stage6) appear to be synced just fine. The converted files have been created using either StreamClip or Quicktime Player on a G5 Mac. Any suggestions on how to get the syncing working properly? P.S. The Silverscreen is connected to my LCD TV through RCA composite connectors--no other stereo device is involved. Thanks.
