[mythtv] Tuner busy in consecutive recordings

[David Griffith]

I've updated my box to the latest SVN yesterday, and last night a show 
that was due to be recorded directly after another show failed to 
record, with the message in the "previously recorded" listing of "tuner 
busy". This is off my bttv capture card - I've got a DVB-T card as well, 
but this station is analog only.

Here's the relevant bit from the backend (sorry, verbose wasn't on)

Any ideas?
