So I installed the AM-21 off-air tuner (first time for me) with THR-22, but as I suspected, my antenna situation is not ideal. So after I chose "local networks" and did the scan, I only found 25 channels.
I repositioned the antenna, and this time found 31.
So I know there are more channels out there, I just can't receive them all at once unless the antenna is physically repositioned. I'll upgrade the antenna down the line.
But I wanted my guide to display all of the channels, even those I can't tune with my antenna. My guide was only showing what was successfully scanned. So I started playing around a little, manually typed in some channels that I knew existed but weren't showing in the guide, like 13-1. It made me realize that I could go into my channel list settings and "turn on" a bunch of channels that were present, but just not getting a strong enough signal during the scan to validate.
So almost everything is good. I can just move the antenna if I see something on one of the subchannels that I want to watch (until we install something outdoors).
About the channels showing up on the guide without descriptions, I'm not experiencing that except for three channels (36-3, 36-4, and 36-5). All other sub-channels have full guide, channel and program descriptions, etc. For a moment, the live buffer wasn't working - but that went away after switching channels. Recording seems to be working as well.
But for those three channels, 36-3, 36-4, and 36-5: the OTA scan didn't find these stations and I had to turn them on manually from the channel list. They are the only channels on the guide that showup with no channel description. Program guide just says 'to be announced' for all programming. But worse than all that, a big "Channel not available" box shows up whenever I tune to these stations. And these channels actually do receive signals with full reception. But I can't record anything, no live buffer, can't rewind, and I can't get rid of the "Channel not available" box displaying over the picture.
