[mythtv] DVB, Live TV Broken with SVN 7050+

[Todd Ignasiak]

 The channel set for startup is a valid HD channel.       Without
making any DB changes, I can run version 7058 and it will work fine,
then run a newer version and it will fail.   I cannot change channels
in mythfrontend, it just hangs with a black screen when I try to watch
Live TV (much like when an incorrect channel is configured as the
initial channel).

The channel it was set for was a cable-only HD channel, which didn't
carry PSIP data.  So, I changed it to another channel, an OTA channel
that includes PSIP.  But, the behavior of mythbackend didn't change.


Here is the output from the working & failing versions of mythbackend:
