One little thing really killed MRV functionality for my family - the inability to sort the recorded program list by source DVR. We really disliked the fact that everything was thrown together. I'm probably in the minority, but it would be so great if we could only sort the playlist by DVR name... The other negative factor for my wife was the inability to watch live TV from the "other" DVR. Right now, I have them hooked up (upstairs/downstairs) with coax. It's not HD, and it's not stereo, but it's great if we have too much recording on one of our DVRs. I think we'd lose that ability with Whole House DVR, no? Am I crazy for asking for this (or am I misunderstanding WHDVR functionality)?
