I'm running the exact same build of raspbian. When I try to watch SVT1HD via DVB-S I get a stuttering image and this in the log of tvheadend:

I can see that the CPU usage is in the about 97-98% for the tvheadend process with top so I guess that it is the cpu that is the problem.I enabled "Full Mux RX mode" but it does not seem to affect this.
My current raspbian build: Linux raspberrypi 3.10.24+ #614 PREEMPT Thu Dec 19 20:38:42 GMT 2013 armv6l GNU/Linux
Tvheadend build: 3.9.313~gf25d918
It seems like I'm running the exact same setup except that I use a dvb-s card instead of dvb-t. Could it be that the drivers for my card are worse?
Are your channels decrypted? I let tvheadend decrypt the channels by connecting to a cardserver (currenlty running on a seperate box on the same network).
Any other reasons why the cpu load is so high for me or is it expected?
