Damn...I was hoping for some others to chime in ;-)

Yep.  I didn't setup DRI until earlier this year, but DVDs were playing
for a while before that.  If I understand correctly, the Xv extension is
purely for 2D acceleration anyway.  For sure, DRI and the DMA via AGP
used is *exclusively* for 3D acceleration in the X-server.

I hate to rub it in, but the playback for me also works well with X11
and SDL video output using VLC (http://www.videolan.org).  They're not
as smooth as Xvideo, but definitely watchable.

Eureka! Ok, I'm no Xvideo expert, but I see something interesting right
away.  My "xvinfo" output looks like this:

I have 14 listed attributes as opposed to your 4 attributes.  I also
have 4 more "supported visuals" than you. I'll bet those make all the
difference in the world :-D

Since you seem to be the tinkering type, try the Gatos Drivers
(http://gatos.sourceforge.net/), as that's what I'm running at the
moment (all you need is the ati.2, but since no binaries are available,
you will need to recompile XFree86 4.2.0 from source).  I could have
sworn I had DVDs working before installing these, but it's possible that
I'm mistaken here.  :-{

If this is too dangerous for you, write me and I'll try to see if I can
dig up all the required binaries and we could just stuff them in your
current XFree86 tree (assuming you're running XFree86 4.2.0).


Best regards,
