Sorry, I can't have been clear enough, its set to four for each tuner. 
i.e. from mythweb

Encoder 1 is local on mythtv0 and is not recording.
Encoder 2 is local on mythtv0 and is not recording.
Encoder 3 is local on mythtv0 and is not recording.
Encoder 4 is local on mythtv0 and is not recording.
Encoder 5 is local on mythtv0 and is not recording.
Encoder 6 is local on mythtv0 and is not recording.
Encoder 7 is local on mythtv0 and is not recording.
Encoder 8 is local on mythtv0 and is not recording.
Encoder 9 is local on mythtv0 and is not recording.

I understand the principle, I'm not sure it applies to the above 
scenario.  I'll add in the mux numbers and check it out, as you say it 
might be padding that's causing it to be > 4, and stopping sequential 
virtual tuner use.

Is this detailed somewhere?

Is there a sql command that will drop out whether my tuners are setup as 
Ronald described?
