TTBOMK, just with a button.

But, before you go to far with changing things, I recommend testing out 
the xawtv/mplayer/whatever approach.  I think you'll find that even 
without Myth doing the recording you'll have about a 2-second delay 
between button presses due to ivtv's and the PVR-x50's interal 
buffering.  So, the difference between doing this outside of Myth or 
inside with LiveTV is 2 seconds versus 3 (in both approaches, it's still 
annoying enough to be less than useful)...

It may actually be easier to branch the output of the STB to your TV, 
then use your STB remote to switch TV source, request the show you want, 
then switch back to Myth which could record it for the LiveTV-style 
pause/rewind/etc you get with the VOD--just don't pause/rewind/etc 
through the VOD.

For recording, set up a VOD channel ( 
http://www.gossamer-threads.com/lists/mythtv/users/232857#232857 ) which 
is only on the video source associated with the STB and schedule a 
manual recording with that channel.  Why scheduled?  Well, without guide 
data, LiveTV will break it into segments that end on the half-hour (i.e. 
first one ends at the top of or half-past the hour, then the rest are 
30-minute recordings).
