It is at least proof of concept that we can detect when the channel
we started up with is off air. The actually channel to tune to is a
topic we need to work through to work out an effective solution for
all.

One possibility is to automatically start into the EIT crawl, but
that still doesn't necessarily give us a valid channel upon entering
Watch LiveTV.

We probably need to implement what you have suggested. Get a list of
channels on that cardinput and walk them till we find a valid one.
Although if we are doing an EIT crawl then we won't be stationary
on a single channel, so we actually need a concept of 
"startchannel when entering live TV"

Will test ASAP.

Hopefully Debian ABI changes won't bite my testing...
