 mythfrontend version: fixes/0.27 [v0.27-178-g6b14852]

 F19 x86_64 local build based on modified rpmfusion specfile

 During playback of a radio recording atop is now showing 98% CPU load,
 mostly as 'idle'.  No visualiser active, blank screen.  The audio sounds
 fine, and keyboard
 response is quick.

 Playing an SD TV recording shows load typically around 25%.  nVidia
 304.119, GeForce 7500LE, no VDPAU.

 My build from the same tarball for my SL6.5/KDE-unstable/elrepo-
 kernel/i686 laptop has CPU load around 10% during radio playback - much
 more reasonable.  Intel GPU.

 These builds predate commit c64141b0c0b7118ee28be2441374727a1af7c44c on
 master, which targeted 'low bitrate' playback.
