[mythtv-users] HDHR QAM: Streams ok to VLC but not to Mythtv 0.22

Hi,
I just moved, upgraded my myth to 0.22, and reconfigured my system to
use the HDHR on Comcast Cable. I've upgraded the HDHR firmware to the
most recent version (20100213), and when I run the hdhomerun_config_gui
with VLC I can watch every channel just fine! However MythTV cannot
tune a couple channels.
When I try to tune the channel on MythTV I get:
Signal 91% | (LAM_V) Partial Lock
The database matches what I see the HDHR Config GUI, that this channel
(803) is on 98.3:
| chanid | channum | freqid | sourceid | callsign | name | icon | finetune | videofilters | xmltvid | recpriority | contrast | brightness | colour | hue | tvformat | visible | outputfilters | useonairguide | mplexid | serviceid | tmoffset | atsc_major_chan | atsc_minor_chan | last_record | default_authority | commmethod |
+--------+---------+--------+----------+----------+--------+------+----------+--------------+---------+-------------+----------+------------+--------+-------+----------+---------+---------------+---------------+---------+-----------+----------+-----------------+-----------------+---------------------+-------------------+------------+
| 2021 | 803 | 98 | 2 | WSBDT | WSB-DT | | 0 | | 19586 | 0 | 32768 | 32768 | 32768 | 32768 | ATSC | 1 | | 1 | 15 | 3 | 0 | 2 | 1 | 2010-02-22 02:00:03 | | -1 |
I have three channels on this physical channel, but only two of them
have problems (the other is #804, WAGADT, on 98.804. Whereas WSBDT2 on
98.248 is just fine). Could there be a tuning problem on this major
channel or is it more likely Myth not reading the PMT correctly? Is
this a bug? The backend log (with -v channel,record,siparser) says the
following:
