Hmm, what's OProfile? 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 selected vdr+softdevice with matrox because I've read so many good 
things about it. 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.

What should I do to get debugging info since there is nothing in the 
syslog. 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.
