Thanks for these tips.
I found that xvmc playback works but with stutters etc.
xvmc complains about not being able to form a surface. (even though I
gave 64M to video mem and told Xine to use extra pages)
I know I have no VT1625 but want to be able to view the content, al be
it on lower res display.
xvinfo gives 1920*1280 or so so there is potential?

When xine works, Myth is the next step in my idea.
