More info regarding my issue with not being able to view OTA channels.  I
have two dual-tuner cards (Hauppauge HVR-1600).  One each one tuner is
analog and one is digital.  My MythTV is configured with 2 sources (1)
analog and (2) digital.  I have both analog tuners successfully bound to and
using the same analog source.  I have one "antenna" tuner bound to the
digital source.  It appears my broadcast scan picked up about 30 OTA
channels.  I also see the station/channel names listed with the tuned
channels.   I initially tried to bind and tune both digital (antenna/ota)
tuners to the same digital source and was unsuccessful with both.  I
currently am only troubleshooting with one of the Hauppage digital in Myth
as I have the other connected to a convert box and TV.

When I view the program guide in Myth, I see the digital/OTA channels listed
with channel names, icons and program listings.  When I try to view one of
the digital channels, Myth freezes up and I have to reboot.

I'm not sure what to look for in the logs, but I did see something that
seemed odd to me in the backend log...

I also saw

The unauthorized error seems odd because my Schedules Direct subscriptions
runs through September and it appears that program listings were retrieved
from Schedules Direct.

The errors listed below seem to have happened around the time I tried tuning
the OTA channel (in preview mode from the program guide).

Would you like to configure the database connection now? [yes]

Any help you can give is appreciated.
