I want to upgrade to HD TV with Directv's whole home HD DVR system. Right now I have no HD capable tvs, but I do have two computers with TV tuners and monitors capable of HD. The final result should be having the DVR on the primary tv in the living room, and the ability to watch tv in the bedroom, the kitchen, and the two computers in separate offices. And eventually everything would be HD. Right now I can only afford to replace the living room tv - will the other two tvs still work? Will I continue to use the standard receivers like now, or can I get the advantage of being able to tap into the DVR with a new HD receiver on the non-HD tvs? Or should I just wait until I win the lottery and do everything at once?
