No, it doesn't have a channel scanner although that would be terribly
useful. :)
The --do-not-filter-channels option doesn't work either. I tried
deleting a channel and
ran 'mythfilldatabase --only-update-channels --do-channel-updates --
do-not-filter-new-channels'
and it didn't insert the missing channel. It seems to be this
is_encoder check that stops
it from creating any channels because is_encoder is always false for
firewire.
It did work last time I set up my zap2it account (quite a while ago).
Thanks Daniel,
Curtis
