I went through 2 Samsung 360s and DirecTV replaced the last one with the RCA DTC-210. I have had no problems with the 210, a much more reliable receiver.
Although I have not seen the RCA dtc-210 in action I do own the H-10 and it has been awesome so far. No jittering, no freezing, no sound cut outs, and the picture is pristine, I've read a couple of bad reviews on them, but maybe some people got bad boxes because mine so far is working like a mexican on an American jobsite.
I know about the NTSC and analog signals. Let me rephrase, the H10 does not pick up analog signals, only digital? That still doesn't sound right but I don't know how to put my question into the right words. *Speaking like Forrest Gump,* "I'm not a smart man techno, but I know what HD is."
