Every time I play MPEG (1 and 2) videos on my PC regardless of the application/hardware, it jumps frames every few minutes. In Star Wars EpII (chapter 20) the camera pans while OB1 is walking in a glass corridor. The frame rate remains smooth then it jumps (skips) for about second and a half before returning to normal. For example, frame 1, 2, 3, 4, 5, 7, 9, 11, 13, 15, 17, 18, 19, 20, 21, 22 etc).
It's very aggravating and sometimes it ruins the entire movie. I did however manage to keep the frame-rate smooth by enabling hardware acceleration but it pixilated the video (ATI X800 GTO).
I was wondering how you guys keep the frame-rate locked/smooth using software render method?
PS: The same phenomenon occurs with H.264, WMV-HD (VC-1) and other MPEG-4 formats when using software render method.
