I'm just wondering about the range of audio/video quality of various UBC (satellite) channels. For example, the Hallmark channel is quite good and looks really great on our 720p/1080i TV. Plus, it has five channel surround sound. At the same time AXN sucks, looks like it came from a poor quality VCD and has mono sound

If UBC is able to broadcast high resolution video on some channels, why doesn't it do so on all of them. Or, is this based on the video they're fed by the various networks?
