No I don't use "Option Composite" nor xcompmgr on this box.
I do use it on my Intel 965GM laptop and seen it interfeers with
mplayer. I didn't 2.2.1 yet though.

Well... I'm not sure DRM is the solution to my problem.
That box is supposed to play my ripped DVD (cartoons for my daughter in
fact) from a NFS share onto my CRT TV. The thing is I'm trying to get
the best results and so DRM/DRI might help make use of the video
card rather than the (poor) 1GHz VIA C3. It has modular-xorg, freevo and
mplayer installed.
If I'm mistaken and DRM/DRI is only usefull to play tuxracer or have a
nice xscreensaver session, then I'm OK to forget it and try to find some
nice CFLAGS for Mplayer.
When displaying DVD quality video, mplayer uses ~60% CPU time and X
about 20%. This seem to lead to audio/video desynchro. When I use a
linux distrib to do such things, the CPU is far more less solicitated
and it plays video OK. So I thought it might be because of the DRM/DRI
support of Linux. But I may just be wrong(c) :-)
Of course, when I use xorg/mplayer on my 2GHz Core 2 Duo (displaying on
the Local FLat Panel) the video is also fluid, but I expect the CPU to be
of any help ;-)
