The soon to come D* MRV might still not be good enough for the OP because the remote receiver will not be able to do full DVR functions, only to playback from the other DVR with trickplays, but no searching, scheduling and programming recordings at the remote end.
I guess it might not be good if people are to lazy to walk into a different room to do most of those functions. Still beats not being able to watch a programming on both TV's and still record items.
