Well, the tuner thread doesn't really do that much that might eat such a lot of CPU time, one would think.
Maybe you can add some debug output in cDvbTuner::Action() and cDvbTuner::SetFrontend() to find out what exactly it is doing when this happens.
few weeks ago I noticed a similar Problem, that vdr eats a lot of cpu power. In my HTPC there is a tt 2.3 dvb-s and a usb-dvb-t stick. I did some tests with dvb-t stick plugged in and without. The cpu load is about 20% higher with the stick. Please tell me if you need more info to find the Problem. Thanks Halim
Can you identify a particular VDR thread that consumes those 20% more CPU time?
I think in my particular case it's really kernel time being spent by the driver trying to lock onto channel 9. I guess the tuning is done to collect VPG data.
