Because of many problems with three different TV cards I had prevoiusly 
- I bought one which claims full linux support - Qbox II by TBS.
After a few  hours I have card working, hovewer I have a problem too.
When I'm recording it seems ok, but when I'm watching through streamdev 
+ VLC, there are errors about buffer overflow. Often it causes viewing 
to stop after a minute or so.
I suspect there is need to set some larger buffers but I don't know where.

Ps. I know why I get:
ERROR: streamdev: protocol violation (VTP) from 127.0.0.1:37275
It's from vdradmin-am which seems incompatible with VDR 1.7.28
