I did a gig last night with the new release, and had many more problems than with the beta version. The program crashed 3 times during the evening, at one point it stopped recognizing the camera input, and the stuttering and slowdowns were much more pronounced than before. Simply selecting a new clip could cause the playback speed to drop down to 3 to 5 fps. Also, when I quit the program, after it asks me if I really want to quit, it simply stops responding and I have to end the program with the task manager.
All of my clips are Indeo Video 5.10 encoded 640 x 480 AVIs.
