that was my second plan of attack, and from what i can tell it all
looks to be ok compared to the other QAM channels. The mplexid even
seems to point to the right frequency look up and the id is the
correct stream id. all of which makes it frustrating. i'm starting the
think perhaps comcast changed the frequency but azap locks onto the
old one fine.

I did notice the following the backend log when nothing is recording,
which looks like it may just be the EIT scanner, but I dunno:

if i have time this weekend I think I'll just go through the channel
scan process again. It would be nice to change the sourceid's back to
1 and 2 and the tuner id's to 1-4.

thanks!!
