Playback Problem Mac Pro + Avid MC
 

Hi guys,
I got a strange problem that I can't resolve. When I am editing on my Mac Pro (Using Avid Media Composer), the playback from the timeline get's faster after about 30 minutes of work for no aparent reason. It can even happen before, when I do work intensively with sound (like mixing). When I shut down AVID and restart the application, everything is fine again - for another 30 minutes ;-( It's probably not an AVID problem, because I had the same Issue before with Xpress pro, and I configured the system to match the latest AVID specifications.

It's somewhat annoying to deal with that 'micky mousing' twice an hour. Does anyone have an idea?

P.S. I am editing PAL SD / Stereo
