Hi Balasz,

the reception is stable and without any problem. It is possible to watch 
(tested on RTL Klub). 

I'm afraid it is a problem with stb0899 linux driver. I've also this card, 
tried to find the bug (I've found one in stb6100.c tuning procedure) but it 
was not sufficient. Also under Windows it was without problem. After many 
hours spent with this card I've bougth HVR-4000, put TT S2-3200 into my table 
and don't have problem anymore.

If you want to do some more test you could contact me off-list.

Below output from szap.

BR,

Ales
