Comment (by pbennett):

 Run the frontend with -v playback option

 Playing back this video I see hundreds of error messages:

 There are similar messages for the subtitles, but fewer:
 {{{

 type(Subtitle) id(DVB_SUBTITLE:94209)

 mythffprobe does recognize the streams, but does show some error messages:

 Some more digging is needed to see why it cannot find the codec for AC3 or
 for DVB subtitles.
