"Retrieve Lineup" won't really work with 90% of QAM channels. It
shouldn't hurt, but it will only figure out the channel mapping
for ATSC channels, usually just the rebroadcast OTA channels.
Nick over at SiliconDust (makers of the HDHomeRun) has some
ideas for creating a free service which maps QAM tuning data
to listings ID's. But it is just in the idea stage right now.

I've been considering removing the separate scan and retrieve
buttons and replacing them with a single button which pops up
a wizard that helps you do the right thing for your recorder
and listings provider. But there are a bunch of bugs I want
to squash first...
