 Hi,

 I noticed that with the DVDs I checked the codec did not set the audio
 language code in 'AvFormatDecoder::ScanStreams' resulting in the audio
 streams being saved in 'Unknown Language' internally.
 This does not seem to be a bigger issue as the OSD gets its information
 about the tracks directly via dvdnav and not via the track map.

 I added some code to get the language info for the track map via dvdnav as
 well in case of DVDs and created a patch for this.

 When testing the patch I ran into a bug that was shadowed by all audio
 tracks always having the unknown language: the stream selection in
 'AvFormatDecoder::AutoSelectAudioTrack' exited early in case the audio map
 contained more than 1 language. I fixed this as well as part of the patch
 as it will only create more problems otherwise.

 The patch is against release-0-22-fixes.

 Please let me know if you need more information or testing.

 Best wishes,

 Martin.
