I received with my bill the invitation to upgrade to an HD DVR (I currently have the 211). I've also been having problems with my 211 detecting my locals from OTA. Needless to say, I would like to make the upgrade. However, a few months back I "moved" to South Bend,IN. Can I get this upgrade and have them ship the DVR to me and then do a self install? Or is this process more difficult than unplugging the old 211 and plugging the new one in? I'm concerned about a service call being paid to the wrong address.
