I am using a Catalyst v3 system on a G4 with two outputs and one internal hard drive containing all operating system and library files.

I am trying to synchronize a movie clip to audio on a CD in the Whole Hog 3 (controlling the server). The playback cues fire off of CD time code.

My problem is that the speed of video playback is highly unpredictable. From night to night, I may get up to a 2x (estimated) difference in video playback speed of the same clip with the same settings.

I have tried this using playback speeds of 'Recorded Speed' (DMX channel 8 @ 0) and other fixed rates.

Can someone lend me some insight into how the Catalyst times itself internally, and what the fix for this problem may be?

Thanks in advance for your help.

Sincerely,

Phil Gilbert
