So my boss decided to upgrade his DirecTV equipment. He had been using an old D12 receiver, with a round dish (18 x 20), and was only getting SD video. When he called to upgrade, the rep told him they'd send him an HR54 (with DVR) and that it would work with his old dish. I had told him before that I thought he'd need a new dish, but when he called the rep seemed pretty adamant that this HR54 would work with his current dish. He got the receiver today and I tried to help him install it. When I got to the setup screen it said "Cannot detect SWM" which really wasn't surprising to me. Because the setup he's got now doesn't have a SWM. He chatted with DirecTV support and they are sending a tech out next week to install a new dish. But even in that chat, the rep was sure that the HR54 would work with his current dish. It's all kind of moot since they are sending out a tech to replace the dish next week. But I'm just curious, will the HR54 work without a SWM? Will it work on the old round 18 x 20 3 LNB dishes? I don't think it will, but DirecTV reps seem to think it will and they SHOULD know more than I do.
