Hello Mephistopheles,

I have a Panasonic Plasma that has Freesat HD and Freeview HD tuners built in. I generally I only use the Freesat as it gives a better picture and sound. I've had no issues with 5.1 content on BBCHD an CH4HD. I suggest that you get a satellite dish up and Freesat Tuner.

Best regards

Frank
