Wow, I have been using ReplayTV units all throughout my house over my network for over 7 years flawlessly machine to machine, room to room, it even asks me which machine do I want to record my show on. But they do not play in HDTV. I purchased the the best DVR's I could find from DTV and I am not impressed. I hope they get MRV technology working soon or at least the rights they purchased from ReplayTV come through soon. I just purchased (3) more H23NC-600 receivers, If I get these on my network will I at least be able to see the one DVR unit on my network from each receiver and can I have two different receivers playing back shows from the same DVR at the same time?
