By the way I would also like to know the answer to the same question in
Mac. As far as I have seen, though, video with GEM seems to perform
always much worst in Mac than in Windows and Linux with any codec

probably knew the cause of this which was not related to codecs.
What did I say ? I thought I said that if your video uses a codec which
requires more CPU than the computer with provide to the codec, then the
codec may look like it wants 250% cpu or something else ridiculously high,
when in fact it may very well need 91% cpu while pd can only provide 90%
to it. This would be because it tries to skip frames and fails
spectacularly at it because the format is not designed to allow it. I
first saw this problem in MAX, but that's because I don't use video files
very often, and when I do, it's almost always in the plain JPEG codec,
which is frame-seekable.
