I am not quite sure if I am starting matroxfb in the right place. For some reason I can not get it to load automatically with udev settings. There is a > I'm using a statically compiled matroxfb.

Like small cpu resource needs since I've got only PII 550. And one reason is also the lack of A/V sync problem. My other vdr is with FF card and I have A/V sync problems every single day at least once. > A few times during the two years, I've seen softdevice displaying fewer > than one frame per second, running at very low CPU consumption.

Log shows that vdr seems to have started normally and I can get a picture which ofcource is a slideshow of still pictures because of the cpu load. Normally changing to a radiostation drops cpu load to some 5% but even that dont have any effect. Only restarting vdr helps. Can poor antenna signal cause something like this? Normally I have cable at home and I and constructing a "new" vdr to be taken to my summer home where we have aerial. At home my dvb-t signal if avfully poor.
