Okay, so I recently replaced my TiVo HD in the living room with a Premiere and moved the HD back into the bedroom. Now I am noticing there is more signal loss on the premiere (we are OTA only) and artifacts. The TiVo HD still picks up all the channels wonderfully. I can't even get one of the channels (CBS) on the Premiere, but it shows up fine on the TiVo HD. What's the deal?
