 After the upgrade to 29, I noticed that mythfrontend will abort in the
 middle of recording playback.  It is reproducible under the following
 conditions:
 * Using a theme '''other''' than the ones shipped with MythTV (MythCenter,
 MythCenter-wide, Terra)
 * Reaching a point in the recording where the resolution changes, such as
 1080i -> 720p or vice versa, commonly seen in commercial breaks or program
 changes, depending on channel.

 I have reproduced this consistently with Steppes, Mythbuntu, Arclight and
 TintedGlass. This also occurs under both VDPAU and OpenGL playback, The
 stock themes are consistently unaffected.

 I have been unable to gather a stacktrace: I don't think it's actually
 crashing, just aborting playback and closing mythfrontend:

 {{{

 }}}

 I'll also add that I am '''not''' configuring Mythfrontend to switch X
 resolutions or refresh rates automatically here: X remains unchanged.
 Furthermore, the OSD is not up when this occurs, nor does it try to
 display, so the theme isn't displaying anything.

 I saw a few changes to add new screens to the shipped themes in 29 but
 didn't see anything that was marked as breaking that would require all
 other themes to be updated.
