 Whenever (as is frequently the case in UK systems such as Freesat (DVB-S)
 and Freeview (DVB-T)) the audio stream of a program changes from stereo to
 5.1 surround sound, the OSD and the actual audio itself does not change to
 accomodate this, which can mean that if a recording begins shortly before
 the 5.1 program airs (when the audio is still in stereo), the audio change
 never occurs and the sound for the whole of the recording is in stereo.

 This is also the case during Live TV as well, whereby if one watches the
 start of a 5.1 program, the audio does not change from stereo, yet if one
 immediately exits live tv then enters again on the same channel, the
 program is instantly in 5.1 surround sound. When a program changes from
 5.1 to stereo (in live tv) the surround channels go silent as expected,
 yet the OSD still shows 5.1.

 XBMC (when showing Live TV from the myth backend) is able to successfully
 transition between stereo and 5.1 and back again without issue (both it's
 OSD and the actual audio updating), yet this is not the case when watching
 recordings.
