Looks like our devs would prefer you to pester V4L upstream to fix the driver...

The tuner MythTV is receiving data from should remain tuned to
whatever channel your STB is outputting its RF feed on. The channel
change script uses the 'freqid' (frequency) value for each channel you
try to change to. Make sure this value is set to the channel number
that you enter on the STB for each channel, and that your channel
change script works.

Note that you can increase useful debug output in the logs by adding
`-v important,general,channel,record` when starting mythbackend - this
may help locate where the error is coming from.

Cheers,
Nick
