The directfb support for mythtv doesn't by default use the tv-out of
matrox cards.
I however managed to get a picture to TV (I have G400) with mythtv gui
through XDirectFB and video through mythtv's directfb support with the
attached patch (which is a hack), but the interlacing was lost and
movements weren't smooth.
I didn't quite like the GUI of mythtv either, so I gave up and installed
VDR instead.
