[mythtv-users] DVB tuning problem

[Anthony Arobone]

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. ?
