Question about my HR-21 HD DVR receiver. This receiver seems to be on the verge of pushing up daisies – but it's been like that for at least three years. It's at the point that I can't even change channels using the up-down arrow on the remote (the command simply won't take). I have to go into the guide, then hope I'll be able to get the channel number entered so I can push "select" and get the channel I want. Oftentimes, when I try to enter a three-digit channel number, only one or two of the numbers will actually enter. And the time it takes to get from one channel to another often can reach close to 60 seconds – the response is often that slow. About the only good thing I can say about the receiver is that the DVR part has always worked great. I seem to remember dropping only one recording in the entire eight or so years I've owned the receiver. But even though the DVR works well, I find myself needing more tuners. Anyway, would I be better off upgrading to a Genie? DirecTV keeps sending me emails saying I am eligible to upgrade to a Genie for free. Also, is a Genie the same as Whole Home DVR? As most of you can tell, I'm not very tech savvy. I operate only two TVs – both are HD – so I guess the right receiver would run both TVs, and would also allow me to record many more programs than my current setup. Please advise.
