Here's my current setup: I have a DVR 625 hooked to 2 TVs plus a 311 Solo receiver -- I also have a rooftop antenna (to get adjacent market channels) and I would run this through the new HD receivers and discard my current DTV converter boxes. I've read an online users manual for the 722k, and its TV connections seem much more complicated than that of my present DVR 625. I currently have a standard def TV set in the living room as my TV1 for the 625 and the TV2 is a 13" HD set in the bedroom. I plan on buying a new HD set for the living room in the next month or so, but is it premature for me to do a DISH upgrade prior to buying the new TV? My current living room (standard def) TV ONLY has an RF input - it has NO composite connections. So, will the 722k even connect to this TV? I've also read posts about the 722k running hot -- does it run hotter than a 625? It is also my understanding that when DISH upgrades a customer to HD, all receivers must be upgraded -- is this correct? I don't plan on replacing the standard def set hooked to the 311 anytime soon. However, DISH has told me they would also replace the 311. Sorry, for all the questions but this is my FIRST experience with upgrading to HD. Thank you for your input.
