VDPAO acceleration in Fedora

Need binary nVidia drivers first, not Fedora drivers. (kmod-nvidia / xorg-x11-drv-nvidia)

Check with

yum provides */libvdpau.so.1

which leads you to install

yum install libvdpao

current mplayer has libvdpao support

Start Nautilus browser inFluxbox

nautilus --no-desktop --browser  &

Convert m4a to mp3

faad filename.m4a

lame -h -b 192 filename.wav filename.mp3

Remove WGA notification

run winodws\system32\wgatray /u

Then delete

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\WgaLogon

Then delete the following in system32

wgatray.exe
wgalogon.dll
dllcache\wgatray.exe
dllcache\wgalogon.dll

And if
SoftwareDistribution\Download\6c4788c9549d437e76e1773a7639582a
exists, delete that whole dir and reboot

Play h.264 on slow computer (mplayer)

mplayer -vo xv -ao alsa -lavdopts fast=1:skiploopfilter=all video.mkv

or

mplayer -vfm ffmpeg -lavdopts lowres=0:fast:skiploopfilter=all video.mkv

I've had better success, framerate and quality with the first one.
