[mythtvnz] Use different tuner for adjacent recordings

[Aaron Whitehouse]

Sorry for a weekend of posts from me, but I'm sure that someone will 
have a quick answer for this.

I have managed to set up 4 virtual tuners on each of my dual physical 
tuners. I want it so that, when there are two adjacent recordings, it 
will use two different tuners, so that it will keep the 5 mins before 
and 10 mins after with the recording.

I'm pretty sure that there is a setting somewhere for this, but I just 
can't see it anywhere. I find MythTV's setup screens really difficult to 
navigate.

Thanks in advance and I hope everybody had a great Easter.

Regards,

Aaron
