CR_Client, you're being oversensitive. Seriously. I would have "off the bat" assumed someone that could not see would not bother getting a new TV either. But, good info about screen magnification and of course guests and family.
That said.. Mythtv version 0.23 as well as 0.24 get 12.99 and 35.99, as long as I check the box to pick up all services when I channel scan (otherwise it's strictly regular TV channels.) It seems like EVERY time I've tuned to it they were reading obituaries!
Regarding 20, yes, I get no guide info either most of the time. Other times it shows as "KWKB...." (the "." are actually "boxes", I think they are null characters. If I tune to KWKB at this point, it screws up MythTV and I have to do some mucking about to fix it. I have guide info turned off for that channel now for just that reason.) The weird thing is, KWKB had guide info for a little while months ago, then it went back away.
Anyone have KYOU "shooting blanks" some recently? I have had failed recordings off 15 the last several days (but I think a few that DID work), this morning I had no program guide info for 15, and when I tuned in 15 I got a clean signal, but black picture and no sound (and after 5 or 10 seconds, ""Error opening jump program file"). I think this means there is no data whatsoever coming through on the channel.
So, my OTA setup. I have a Grey-Hovermann antenna (somewhat older design, not the newest one that is better for VHF-Hi...). This antenna is indoors. It is hooked up to a 20dB amp, then via short length of cable to a high quality USB TV tuner (excellent multipath handling, and sucks in the weak signals very well..) This keeps the coax run short, instead of 50 feet of coax I have short coax and ~50 feet of USB cables.
So, initially i got 2, 12, 15, 20, 26 (usually), 28, and 48 (So, CBS, PBS, Fox, WB + AntennaTV -- but no program guide so I can't usefully record them -- , WB again + ThisTV, Fox again, and Pax. Well, *initially* I got 7 and 9 too, before they went back to VHF. Grrrr.
I then found an aim where it was not particularly aimed towards Cedar Rapids, it must be picking up reflections off metal siding and such; I was getting 2, 7, 9, 12, 15, 20, 26, 28. But 7 (NBC, ThisTV, and MeTV) and 9 (ABC and 9.2) recently became too unreliable, I have read stations tend to be a few db higher in winter, and I guess I needed those couple db. Plus I enjoyed several shows on 8.3 when they briefly came in.
So I've recently aimed towards the quad cities, and now get 6, 8, 12, 15, 20, 26. So, I'm getting NBC, ABC + AntennaTV + MyNetworkTV 16 (WQBD-LP), PBS, Fox, WB + AntennaTV (no program guide), WB again + ThisTV. Only thing really missing is CBS. But I can watch the 1 or 2 shows on there on Hulu. I get far more entertaining shows from WQBD-LP than off CBS to be honest.
