Wife had dish when I moved in. Ion channel is on a lot (SD only). I notice a lot of times that with steady tones/music, that the sound is "warped" or warbled, or wobbly. Don't know how best to describe. It's just weird. Is this the receiver, or some strange consequence of re encoding? I hear it across many SD channels, on commercials (including & especially the dish ones). The service isn't otherwise bad. I'm a long time fan of dish, even though I'm not sure it's worth the cost compared to cox cable. Anyway, all that is for other topics. I'm just curious if anyone else notices this, and knows what the deal might be.
