Well I'm making progress,sort of, but no explanation yet!

Built the latest from git, installed and run.  Tried my "broken"
recording and it played every time.  Then I realised I had not applied
your patch!

Uninstalled, installed from mythbuntu ppa, tried the same recording
and, as expected, on the second attempt I get a segmentation fault.

Removed the mythbunutu version, installed my local build (still
without the patch) and the recording plays back fine.

--version outputs are below.  The complied in option differences are

mythbuntu has extra:
using_crystalhd
using_firewire
using_libcec
using_libxml2
using_xrandr
using_xv
using_vaapi
using_libass

I'll keep testing and see if I can get anything else useful.  Any
suggestions gratefully received.
