The below should work for most cases (if memory serves me right):

Actually I also have some problems, but since I haven't had any time to try to 
figure it out myself I haven't reported it. driver from 021208 and vdr 1.1.1x 
was rock solid. But I wanted the latest and greatest. With pre2/vdr 1.25 and 
also a pretty recent CVS driver and vdr 1.26 I have some problems.
1) vdr sometimes hangs at channel switches. Sometimes It work for a couple of 
days and sometimes only minutes. The output freezes with the osd still 
showing. The logs doesn't show anything. Vdr is still running. kill -9 and a 
restart of  vdr fixes things. This seems similar to your problem.
2) vdr dies without leaving any trace. This happens more seldom. Nothing in 
the logs and no core file.  
3) (I just remebered this one). Sometimes when I start a recording vdr 
freezes. My /video is nfs mounted and usually the disk(s) have to spin up. 
Maybe this could affect things? 

One person who has the same board as ours had severe problems (tuning) with 
the latest microcode. When he switched to an older version it got better.  
This is probably unrelated, but just in case....

I'm sorry that I don't have any solution for your problem but at least you're 
not alone:-).
