[vdr] fbxine video disappears audio and remote still working

[Hu-Emulator]

Currently running vdr-1.3.41. I have vdr-xine-0.7.6 and cvs xine-lib and 
xine-ui. Applied all the patches and compiled xinie-lib and ui.

command line to stat xine:
fbxine -V vidixfb -A alsa "vdr:/tmp/vdr-xine/stream#demux:mpeg_pes"

Using matrox g550 video card.

Nexus S dvb card.

I get perfect video for about 30 min then I get errors and loose all video 
but still have audio and also can change channels with remote??
