Timing different on desktop versus server

When a flash movie with embedded .flvs is tested on the desktop, audio (seperate mp3 file), flash animations, and video (flv) synch up correctly.

When same file is moved to the server, audio still plays at correct speed and animations are at the right speed, but the video seems to be moving at a much slower speed (maybe 1/4 or 1/8 the original speed). I can somewhat mitigate by increasing framerate to about 120 and extending the animations, but that's not a real feasible solution.

Anyone have this happen to them or know why the swf would be slowing down the flv only on the server? (P.S. - not a loading issue)
