> Hi,
> 
> I have tried for weeks to make this card work with Tvheadend and now recently with Myth TV on the following configuration:
> • Intel(R) Core(TM)2 Duo CPU     E4600  @ 2.40GHz
> • Ubuntu desktop 12.04
> • Kernel version 3.2.0-36-generic-pae
> • KNC1 TV-Station DVB-S2 Twin card
> http://knc1.de/d/produkte/digital_dvb_s2_twin.htm
> 
> KNC1 are providing a Linux driver on their homepage http://knc1.de/d/download/digital.htm#linux
> 
> The driver builds and loads fine. I’m able to scan for channels. It’s even possible to record TV (with both Tvheadend and Myth TV backend).
> But here the fun part ends. When I play back the recorded files they do not have proper quality. HDTV is useless – even standard TV resolution is not acceptable.
