I see similar problems here, caused by the DVB driver using too much  
kernel time when a card cannot tune a station.

My primary DVB device can tune all channels. My secondary cannot tune  
all, for some unknown reason. Thus I have set up the secondary DVB  
device as the main device used for normal TV viewing, since I don't  
want VDR to try to tune to get EPG data on that card. But when  
playing recordings, VDR uses the first available card, so the problem  

There is a similar problem, if I try to record a channel on a card  
that cannot tune to the channel, VDR segfaults.
