I think this idea is great!

Nearly all people (besides us, of course...) use about 4 buttons on
their TV remote. (1) Off/on, (2) *one* of the channel change buttons,
(3) volume up, (4) volume down

Fast livetv channel changing ability would certainly help people
transition *to* MythTV and would definitely boost the initial WAF of
MythTV. ...and more new users means more developers in training to
work on more important tweaks:)
