A coworker and I were comparing notes the other day. We both have Cox (So Cal), and both have the Motorola 6412 DVR. We've both noticed that chanels 702, 704 & 705 will often have bad distortion during prime time hours. So bad that neither one of us will record in HD. It get so bad (frequently) that you can't pause, rewind or even FFW once the distortion starts. 707 and 711 don't seem to have the problem. I'm using HDMI to a Philips LCD Ambilight at 1080i. Any thoughts on this?
