I currently have a 2 room system with an HDDVR and an HD receiver. I tried the MRV and it is basically unusable with HD. I'm trying to figure out if anyone knows what to say so that I don't have to pay 200 bucks to go from HD receiver to another HDDVR. I don't want to add a 3rd room, just want to somehow change the HD to HDDVR. Anyone with ideas to help?
