Go back and reread what I said.  I did not say Myth's use of DirectFB
was impossible (indeed it is great) nor did I say Myth's use of SDL was
impossible.  What I said is that QT did not support writing on either an
SDL surface nor a DirectFB surface, which is the disappointing part
because that makes getting the OSD on DirectFB impossible.

I'm really not sure how displaying the OSD on an X-server on a G400
"matroxset" mangled framebuffer is supposed to work with the DirectFB
"layer 2" CRTC2 output anyhow since I thought the two were mutually
exclusive (i.e. framebuffer/X11 needing the maven kernel module and
DirectFB requiring no maven kernel module).

I did try it and all I got was the video playing in a small square in
the top right of the screen.
