as i recall, you can't use matroxfb_maven and matroxfb_crtc2
simultaneously. have tried to rmmod matroxfb_crtc2? i certainly can use
mplayer with -vo directfb using the afore mentioned setup.
i've also tried using mythtv with X but i find the picture quality of
the tv-out a lot better with directfb.
now i just realized that if you're using a 2.6 kernel, you might need to
patch the matroxfb_maven module, i don't know whether they have the
bellow patch already in the kernel tree. i found it in the kernel list
sometime after 2.6 got released but at least with 2.6.5 it still was
broken.
