I've tried that and could watch them - at least what the cpu allowed, e.g. QVC HD worked flawlessly with ~60% CPU but Das Erste HD had ~100%, but I knew that this could be so. That means it works ... at times because sometimes I don't get a signal in TBS viewer too. I'll try to increase the signal (although I bought this antenna some month ago to be ready for DVB-T2 ...) and keep you informed. EDIT: Does the CrazyScan-graph tell anything about the signal strength? Or is there another tool you can recommend to get quick infos on that?
