   Dunno how to really do what you are asking to do. I've asked before
how to tell which tuner even recorded a show (for debug reasons...)
and no one seemed to know how to do that either.

   On my system, under Manager Recordings, Upcoming Recordings, I see
the numbers 1 & 2 in the right hand column. It has been my guess that
these numbers are telling me which tuner is going to be used. On my
system tuner #1 is not used all the time. It seems, from looking right
now, that on even days it's used every time and on odd days it varies
back and forth between #1 and #2.
