Hello Daniel,
When I tune to the PBS channel, there is only a black screen with the
signal monitoring code stating "(Signal 100 % LaGv) Partial Lock".
After few seconds, I start seeing mpeg log errors (as noted below). The
mpeg2video errors don't always show up, sometimes I just see
prebuffering messages only.

You need to set atscsrcid to 80*256 + 6 for this channel, not
16*256 + 6.
It looks like the VCT tables were munged with by the broadcaster,
which is why they are on 80 and not 16. However, I'm surprised the
channel scanner did not do that for you. Can you send me the logs
from "mythtv-setup -v channel,siparser" when you do the scan, and
tell me exactly which scan and what params you used. And also send
me a dump of the portions of the channel and dtv_multiplex tables
generated during the scan.
Hello Daniel,
Here are all the bits you requested. For reference, the
