that is the question. I currently have one HD DVR (I believe an H21) and one HD reciever (non-DVR). My HD DVR has been acting screwy lately (freezing and not powering down correctly) and I want to upgrade. I have heard there are a lot of bugs with the H34. I currently do not have DECA (but I do have a very good wireless N setup). In order to upgrade to the H34, and get the multiroom setup would I need to have DECA setup? Does DTV charge a ton for the installation? Should I just get the DVR replaced and if so, can I get multi-room without having DECA installed? Having a hard time deciding any help would be huge. Thanks a ton.
