Re: h264_vdpau not
I've done 2 things, so i can't be sure which solved it.
1. Download the codec library from the mplayer website and re-install it.
2. (More likely) Clean checkout from svn, so it's both a clean copy, and newest (30311)
This is amazing, from 100% cpu usage on 1080i to 3% usage with E7200 and 8400GS.
