This is a secondary issue, probably caused by the tuning problem, and 
I've seen it too (after loss of signal)... When the DVB card fails to 
deliver data the backend somehow goes into a spin and takes all the CPU 
it can get. Might be something wrong with the poll/read loop in 
dvbrecorder or dvbsiparser, or maybe a bug in the DVB drivers. I did 
some investigations some time ago but couldn't figure it out, and now I 
haven't seen it for some time so I'm kinda hoping there was something 
broken in the DVB drivers that is fixed now. :)
