Memory was the first thing I suspected but memtest went through 10+ 
times without a fail. Heat shouldn't be a problem either. There's a big 
efficient, noisy fan in the back of the case.

The machine works fine when dvb is watched with dvbyell 
http://www.dvbyell.org/ which has cards set to fixed frequency ie. card1 
-> 152Mhz and card2 -> 290Mhz. At least for me the problem occurs only 
with apps like mythtv and vdr which change the frequency of the tuner.
