Hi All, I just discovered I am having the same or similar issue. I have a video I edited last week and have already rendered it once. I am now trying to make some changes to it and the video will not play in the program window. It is frozen on the same frame, audio is fine. If I click on the video in the program panel it will play but only until it reaches a transition either on that layer or any of the layers above it. The it freezes and I have to click the program panel again. This is a TV program that has about five layers witth many many cuts. Also, in the spirit of giving you as much info as possible, There is a white box (like resize or scaleing handles arouind the clip in the program video. Don’t ever recall seeing that before. I am using CS3 for about 1.5 years and never had 1 issue with it until now.
Thanks
D
