Comment:

 I'm going to mark this as fixed - sorry that it's probably not fixed the
 way you might prefer.

 MythTV has some ever-evolving logic to try to minimize tuning failures in
 Live TV.  This logic is based on the sometimes flawed assumption that if
 the channel was tunable in the past, it is probably tunable now, and the
 logic currently involves the hidden setting DefaultChanID as the default
 starting channel, and the database column cardinput.startchan as the last
 known "good" channel on the tuner.  That logic doesn't always work, most
 notably when a previously good channel goes off the air.

 The best way to handle this might be to initiate some kind of channel scan
 upon tuning failure, or some dialog to let the user pick an alternate
 channel.  In a sense, the latter approach is now implemented for Master /
 0.28 via #11913, which allows the user to start Live TV on a specific
 channel from the Program Guide.

 (Unfortunately, #11913 can't be back-ported to 0.27-fixes because it
 introduces a new translatable string in the Program Guide menu, and I
 didn't find a suitable already-translated string to reuse.)
