I discovered photobooth in this computer and how it can record video. It worked fine for a while, but now, when I try to record, it won't record everything. It will record for 20 minutes or so and when I hit the stop button, it will only save maybe 30 seconds or 2 minutes of it (A random number). Does anyone else have this problem? What program can I use besides this one to record some video with this built in camera?
