[mythtv-users] 2nd source not updating through SD

[Enigma]

I have recently signed up for SD and I am having a problem pulling down 
all my listings.  I have 2 sources that stem from the same lineup, one 
is a regular analog cable source that inputs directly into a PVR-500 
(and PVR-250 on another backend, but that's probably not relevant here) 
and the other is a cable box that feeds into the composite input on the 
PVR-500 and just tunes a single channel.  With Zap2It I used two 
different lineups for this setup but having switched to SD I would like 
to use a single lineup using caching to populate both sources. 

Upon upgrading, I deleted the old sources and added my new sources as 
described in the documentation 
(http://www.mythtv.org/docs/mythtv-HOWTO-24.html#ss24.4).  Everything 
seemed to work correctly, I ran a manual mythfill and the schedule (on 
all channels) was populated correctly.   However, when I looked at the 
listings today the data for the single channel on the second source is 
now missing it's data (perhaps when an automatic mythfill ran 
overnight).  I attempted to manually update just the source that was 
missing data using ># mythfilldatabase --remove-new-channels --sourceid 
2 --refresh-all but I still have no data for that channel.

All channels are working correctly and the input connections are all set 
up right.  I followed the documentation closely and my sources seem to 
be set up correctly.  Where do I look to start debugging this issue?  
Although I set a log location in the preferences, I can't seem to find a 
mythfill log.  Is there a default location where this might be?  Is 
there anything special that needs to be done (other than 
--remove-new-channels) to run mythfill?
