Is there a hard date on when we will lose the current signal and our old receivers will stop working? I am looking forward to upgrading to HD and a getting a new HD receiver. I'm not a typical user I guess though, because I've not gone HD thus far because I'm not dis-satistifed with the current SD video I get via DirecTV and my SD TiVo DVR. What I'm afraid of is after reading for a while on this forum and others is that the changes I'd have to endure from a software standpoint could be very annoying going from a TiVo DVR to a DirecTV branded one. My thought was to maybe keep my SD TiVo in the bedroom and use the new DVR in the front room. That way if/when the new DVR drops the ball on a recording I'd have my faithful and never failing TiVo as a backup. From what I understand, this would require me to have the old dish and LNB as well as the new stuff at the same time and that's not a problem. However, at some point their shutting off the old feed, right? At what point will I lose the ability to have my current SD TiVo recording from DirecTV?
