This doesn't seem to be the case. I have redone my test using the movie clip that is shipped with psychopy in order to minimize the chance that my movie encoding is the source of the problem /usr/share/pyshared/psychopy/demos/coder/stimuli/jwpIntro.mov Even with a frame size of 40x30 it reports dropped frames (although at this size I cannot confirm their presence visually anymore). I tried h264, mp4, mpeg2 and mpeg1, which should be increasingly easier to decompress, and I tried different bitrates -- nothing makes the clip play smooth. At the same time I see no significant CPU usage on an i7-3667U CPU @ 2.00GHz. Most of the tests happened on machines with INTEL hardware, but on NVIDIA hardware I see the same issue.
