I just tried to do a movie at 480x272 and when I went to check with QT the screen was blank (white) with audio. I moved the slider around and it went to black, but still no audio. I used the 4th PSP profile (which I have used many times before), AVC/H264. I've really been disappointed with CDM. This and the lack of Disney MixMax support has really turned me off to Slysoft lately.
