[mythtv-users] 3 Mux but recording schedule indicating using 4 tuners?

I recall a number of discussions about the tuner logic and tuner 
allocation, with some enthusiastic threads about this. The developers 
always (in my view) had the last say as where they'd taken the code was 
difficult to improve. (Considering the below makes me wonder if the 
tuners might be better to be more floating, "first available" but with 
recording priority? It seems when a tuner is locked to a MUX then it 
could and should be the source of all channels sought form that mux?)

We have 3 Mux here with all channels here in NZ. With the Rugby World 
Cup on the tuners are getting quite some use, as the competing channels 
are putting on some good stuff to look to head off the competition(!).

The interesting thing is tonight's recording schedule is specifying 
using all 4 tuners.  My expectation was that there would never be the 
need for the 4th for recording channels, however for some reason the 
fourth is now planned to be used, as seen in mythweb, recording 
schedules.  Would, could or should that be correct?

My backend has 2 PCI Hauppauge WinTV Nova-T 500-HD Dual DVB-T tuner 
cards, which I've named D1 to D4. This is mythbuntu 10.04 / mythtv 0.23 
fixes 26863, perhaps this has been advanced since?  My planning had the 
4th Tuner available for Live TV priority, which is fine for one Frontend 
(but if two frontend's want Live TV the first commands the Mux, so the 
2nd has a limited set of channels available by default).
