I'd have to agree with Bruce, that the EPG is probably the right place to add
enhancements, if desired.  No need to re-invent it.  And there are already
standards for the up/down/left/right navigation keys.  It would be a step-back
to add new navigation keys, since those of us with remotes may already not have
enough buttons to control everything about MythTV that we want to control.

Perhaps...  an "alternate-alternate-EPG".  Best yet: "EPG theme support" that
lets you define the screen and guide data locations (possibly even allowing
overlaying the guide on a full-screen tv picture?)
