Ok hoping someone who has this receiver can answer this question... First I've tried the searches, but all I seem to find are questions about 'how to', or 'issues'... but nothing about features or specs ;( First.. I'm currently an E* customer, thinking about switching to D* now that I have my HD TV and the rest of the setup.. I've got one 50" HDTV in the main room, and 3 other TV's in various other rooms in the house. The Main TV is currently being fed directly from my E*'s Receiver Component video outs... I have a 2nd output, coming from the Coax out, going into the wall, which in turn goes up into the attic, into a standard cable splitter, and back down to the wall outlets in the other parts of the house.. in effect 'back feeding' my other rooms.. I use a RF remote to control the Recever when in the other rooms. 1) My first question, and probably my biggest.. is do ANY of the D* receivers (HD DVR only), have a Coax output? The Rep on the phone said they did.. but I happend to see one today in a local retailer (the HR21 I think it was), and it does not have a coax.. in fact none of the receivers they had do. If not.. does anyone know of a solution to 'downconvert' another output (assuming the receiver has one) to a coax signal? I can find lots of converters going the other direction.. but nothing that converts a digital down to coax. 2) HDMI output. Exactly what is output from the HDMI on D*s receivers? I have heard that some of E*s receivers only output Dolby 2.0 through HDMI and that I'd have to use the optical audio out in order to get 5.1 Dolby. Is that the same on D*'s receivers? 3) Models... I see from the forums above there seem to be 2 different models..HR20 and HR21, but both seem to have 2 flavors HRxx-200 and HRxx-700, what is the difference? Are there any other HD DVR units? Not sure what I should be asking for from D* when I call to setup my service... I can't seem to find any 'spec' sheets (which would answer a lot of my questions). Any help would be appreciated.. right now I'm still on the fence between D* and E*... Price are slightly lower with D*'s current promotions... D* has better selection of HD that I watch... but E*'s receiver seems to be more detailed (not sure if it's better yet). The ability to watch TV in other rooms without any extra fee is a big deal to me at the moment. Thanks in advance guys.
