Hmmm, now that you're talking about. I can confirm this problem. 
Although not with 1.3.10 but an earlier version (do not know which one).


I had a channels.conf containing all (!) of the astra and hotbird 
channels (I let vdr add them automatically). Due to this high cpu usage 
i cleaned up my channels.conf and the problems were gone.
