Good idea.  There was some chatter a while back about an auto-pids 
patch.  I had assumed that this was the goal of that.  Perhaps dig back 
and find the author and ask them about where they were going with that?

Possibly.  However, the scanner is non-trivial and probably best donated 
to the wider community ?  Look at the "scan" app and see what needs 
improving on that, and then wrap the whole lot I think?

Also look at VDR and see how they shoe-horn things there.  I'm not 
denying that it's a bit of a hack, but I think there is little 
motivation or willingness to make big changes to the code base, so in 
order to work this in I suggest that you look at minimising the amount 
of work/changes required as much as other stuff...

Good luck.  I think this would be an excellent addition to Myth - badly 
needed in fact.  However, please initially consider the easy option to 
simply capture the output from scan, or simply import a pre-created 
channels.conf file.  This will give you good experience as to what the 
problems are on the Myth side
