Must be Xv support. I am also talking about playout only. If I'm recording
also I used to notice about 10-20% increase in cpu usage on the athlon 1300.
I'm also only playing out 640x480 :( Also I haven't really looked at X cpu
usage before because it was nothing significant. It is now however. This is
with no post processing at all.

Usually the pattern is a little 2-3% blip every 10 seconds or so looking at
gnome system monitor applet, the rest of the time it's zero.

I think this weekend I will try reverting back to the release version and
see if this is all my imagination or what, since I'm looking at the cpu
usage on a different machine now.
