[mythtv-users] Multiple tuner query (PVR250 + USB DVB-T)

[Mark Kundinger]

Well, the "c" key will swtich between inputs on one card.  The "y" key
will switch cards entirely.

Unfortunately, I have not personally dealt with a system where
different tuners were used for different channel ranges, so I don't
have more insight.
