I don't think mythtv will do this for you but I can imagine you could
set this up with lirc and an external script.  Something like:

1) Map your STB commands to an unused remote button
2) Point LIRC to a script to execute when these are pushed
3) Do a query to find which STB is displaying LiveTV
4) Send the right/left/up/down/select command to the STB

That assumes you know how to send these commands to the STB. The
channel change script probably only knows how to send numbers.

I imagine LiveTV recordings are not really "live" so it would probably
take awhile after you press the button before you see it on the
screen.  That would be odd but maybe usable.

I use the OnDemand occasionally to record a missed show and it is
really crazy trying to start a show upstairs on the cable box without
seeing it on the screen... :)
