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.
