The resolution of the starting file is 480x480. In an attempt to see if the
problem is decoding or the re-encode, I renamed a MPEG-2 file created by my
PVR-150 to avi so VLC would stream it. Still 100% CPU utilization. I don't
think a decode could be much easier than that. If it's fair to then assume
that the problem isn't the source file, is there something wrong with my
VLC?
