I now have a Sanyo Xacti HD2000 hi-def camcorder that produces MP4 files (up to 1080p, but 720p is what I am currently testing). I installed FFDSHOW and did the registry changes to play MP4 files in VMC, but the sound runs ahead of the video. Of course, it works fine in WMP and other players. After much searching, I cannot find a solution. Any suggestions welcome. Thanks in advance.
