Every two and a half minute, my syslog gets an entry like:

Jan  3 06:04:40 htpc kernel: cx88[1]/2: cx8802_timeout
Jan  3 06:04:49 htpc vdr: [2369] frontend 1 timed out while tuning to  
channel 9, tp 578

About 30 seconds before i get this entry, thee's a vdr thread that  
eats about 25% system cpu time. I'm wondering what it's doing with  
all that processor power? As I'm using budget cards with softdevice,  
this has an effect on tv playback.. It only happens when I'm using  
two cards at the same time.
