Video is pretty much garbage. >> However if I remove CAM then everything works perfectly (except I can't watch >> encrypted channels). Hi Marko, thanks for the hint with your patch, I missed this. I have some stability problems with my HD card too. I will try the patch as soon as I find some time, maybe next weekend. BTW: the official statement from the TerraTec support to Linux is: No support for Linux OS, no support for developers for Linux. No further emails will change this point of view. I can just say: Thank you TerraTec, great support!
