[mythtv-users] can watch live tv but cannot record on some channels

[Patrick Mansfield]

Hi -

My setup was working fine, but a few weeks ago recordings for one channel
stopped working, even though I can watch live TV fine for that channel.

I have a QAM pchdtv tuner, running current 0.21 from svn, on an up to date
fedora 7, with comcast. A single combined FE/BE setup.

I tried both channels on that mplexid, and they both have the same problem - 
I can watch live tv, but scheduled recordings end up with no file.

Other channels are working fine.

I don't see anything obvious in log output for "mythbackend -v all", but
it never seems to actually tune the channel - I never see the
CreatePATSingleProgram() logged like I do for good recordings.

Any ideas on what to look at or change?

It's possible (or even likely) that comcast changed something, but in that
case I would have expected live tv to also fail.

Thanks ...
