 I'm running trunk with Paul Kendalls patch from Message-Id:
 <200907081851.01172.paul at kcbbs.gen.nz> on mythtv-dev at mythtv.org. I'm
 running Myth on the digital terrestrial transmissions in norway.

 Mythfrontend dies on certain local broadcasts, and no preview is generated
 for them. Attached (hopefully) is a complete log from starting the
 frontend, navigating to the offending recording and pressing enter. The
 frontend is running like so: "/usr/bin/mythfrontend -v
 important,audio,libav,extra".

 I'm running Myth on the digital transmissions in norway. Mplayer
 identifies an OK recording like this:

 This command:

 ----

 {{{
 $ mplayer -frames 0 -identify /pub2/mythtv/3009_20090709145130.mpg 2>&1 >
 nrk1.log

 }}}

 Gives this in nrk1.log:
