I'm a long-time UTV user (nearly six years now!), on my second unit, and I've never seen this problem before. While watching either a recording or a live program, the picture is mostly pixelated. You can hear the sound just fine, and usually the first frame or two look all right, but after that the screen is mostly green with some outlines visible for moving objects. It's just the program content that's affected, not the guide or menus. I verified that this happens for all recordings, including those that I know I've watched before without this problem. So I unplugged the unit for about fifteen minutes, and that cleared it up, but I'm wondering when the other shoe will fall.
It sounds to me like a video signal processing chip of some sort might be failing, but I haven't heard of this particular problem before. (I've dealt with bad tuners and hard disk failures, and this is obviously neither one.) Is this something that CCS might be able to fix?
