I was just looking at the new backend/frontend work. If I wanted to modify the
patch so that it changes automatically if you have less then 2 keys, is this
what would be involved:

* Patch tv_play.cpp to call m_context->MaxChannel to get the largest channel
number (presumably cache this value too).
* Add a MaxChannel func to mythcontext.cpp that sends MAX_CHANNEL command to
the backend (as frontend does not have a db connection right?).
* Add the MAX_CHANNEL command to mythbackend program.
* Add a MaxChannel() func to tv_rec.cpp.

Let me know if I'm on the right track..

Cheers,

Alex
