Thanks Dave for your reply. Yes this is only a ram preview issue. I suppose the word “play” is not the right one to use. It happens when hitting the “0” letting it cache and then hitting either “0” or space bar again. I’ll try taking out some of the footage in the comp and see if something is causing a problem. However, on my macbook pro, the same comp ram previews just fine. Adittionally, on my XP system it does fine as well. So it’s disturbing to see that I have a new multi-processing machine with lots of ram, and can’t even get a solid ram preview. It is worth noting that on some of my other projects, it previews without hanging.
All of the footage is QT with animation codec so I don’t think it is a problem there.

had some other gripes similar to mine about multi-processing, but no solutions offered.
