[vdr] Lot of distortions in replay

[Kartsa]

Lately I have had problems with recordings as if there is bits and 
pieces missing from the recording. Sometimes there seems to be missing 
30sec or more. And these dropouts comes sometimes frequently like every 
minute or so. Femon shows good signal and snr and ber is quite low also. 
I remember sometime been reading about dvb card sensitivity to power 
supply. Does anyone have similar experiences?

I'm using vdr-1.4.6 with a couple of technotrend/hauppauge dvb-c cards 
(Nexus-CA and Nova-C). I'm also using dxr3 as video out.
