I have been recently started to notice alot of noise in the picture especially on HD channels and I am wondering if this is due to compression or is it possible that there might be something wrong with my receiver? I really notice artifacts on the Centre Ice HD channels (866-869) during any motion on the ice. I see alot of "blocks" and noise when there is any type of movement of the camera on the white ice. I also see some of this noise when watching a HD football game. My tv is a Panasonic 1080P plasma, only two weeks old. The "noise/blocks" on the hockey do not appear on CBC or TSN games and are not on the HD channels when viewed with a S-Video cable, just actual HD. Could this be a receiver issue and if so, what will Bell do for me, other than nothing?
