So I finally decided to take the plunge and connect my OTA antenna to my HR-20 100s. It has not gone well at all. Some background: it is a new RCA powered HD antenna. I had it connected to my Samsung HDTV's ATSC tuner for the last couple of days and it worked great. I picked up all of the local HD channels I was supposed to get. However, when I connected to the Antenna input on the HR-20, I get nothing. I connected the antenna, ran the "sat & ant" setup for the Antenna, entering my zip (27606), letting it scan, etc. The box found the list of channels that should be available to me and I clicked "done". However, nothing at all is coming in. When I run the signal meter, not a single channel is receiving anything at all. I ran the info test and it says the OTA tuners are "OK, signal at 0%". What is going on here? Am I doing something wrong? Also, what is the OTA tuner #2? There is only one connection on the back. Sorry if all of this is covered somewhere, I swear I looked! (btw, the folks at DTV were completely NOT helpful with this topic.) **UPDATE** See 2 posts down for my rant.
