ok, so I have a video that had it's audio and video recorded on different computers. The video was recorded at 1080i 59.94. Recorded in final cut pro. The audio was recorded in Protools and the session's time code rate was set to 29.97. So I exported the video as an Apple Intermediac codec 1080i and 720p. When played back on catalyst, with the video and audio synced, the video after about 3 minuets starts to look off. It gets worse and worse as time goes.

I changed the catalyst play rate to 29.97 and that seemed to make it worse.

Any ideas?

Thanks for the help.
