Does anyone know how to make "searching for signal" message to go away? If I'm watching something that I've already recorded (for example, if there's a tropical storm outside), I really don't care (and have already figured out) that there is no signal. One quick quirk was - the DTV screensaver actually came on while we were watching the prerecorded show! (I assume because the "searching for signal" message box was displayed.) When I got this box, I was impressed, but you know - Dish is starting to look good (considering their HD-DVR is actually affordable ($200 vs $400) and their HD packages).
