Questions about this. I moved and needed wireless to 2 rooms so had to drop D* after 10 years with them. Currently using ATT wih 2 wireless recievers and they work quite well, but miss the interface and usage of D* recievers, and the PQ. 1) Does this perform the same functions as a DVR, even though it is not a DVR? ie: List, record, doubt change buffers 2) Is it HD? 3) Would I be able to do VOD on it? 4) I still have a wireless cinema kit, would I still be able to use it with wireless recievers? I'm hoping the answers to all this is yes and I am ret to get rid of ATT.
