I'm afraid it isn't working! I have had some serious consequences of running MC with TV. I have had two system crashes, something I have never had with any other application. Whilst playing live TV, the video freezes, the audio plays a short sample of audio over and over, then the PC crashes and restarts. Every time, the live TV will play for 1 to 2 minutes then goes into this state. The PC doesn't always restart but does not respond to any inputs and has to be hard reset. I will post a log later.
Nick.
