Recently time warner did something to NBC-DT and all my atsc tv's with
tuners couldn't tune it. As it tunes out they renumbered it or changed the
frequency or something, I'm not entirely sure. But when I rescanned with my
tvs one tv got it back as the same number, 39-1, while another tv it changed
from 39-1 to 91-2. But I still can't get mythTV to find it. I have a
HD5500 tuner. I tried rescanning from mythtv-setup and it wont' find it. I
even tried deleting all the channels from that source line up and then
rescanning and it still wouldn't find it.
I used dvbscan to create a channels.conf, and I can tune NBC-DT just fine
with mplayer. Here is the appropriate line:
NBCDT:627000000:QAM_256:49:52:1707
Now, I'm not sure what to do with this channels.conf. I tried importing it
with mythtv-setup but it just segfaults. Oh, I'm running Gentoo 2.6.25, and
mythTV 0.21_p18314, which pulls from SVN, and I'm assuming that's the svn
revision number.
Next I tried inserting it directly into the DB, while now it shows up in the
guide (with data too), it still won't tune. Here are my DB entries:
The one in question is chanid = 3164. And I wasn't sure what to put in for
freqid, so I just put in 39. ?
