The three letter language codes are derived from the codes broadcast
in the PID definitions (see pat.c under 'case SI::SubtitlingDescriptorTag:').
The full names are derived from the EPG's component descriptors (see
eit.c under 'case SI::ComponentDescriptorTag:').

When it comes to presenting these to the user, they are collected in
menu.c, function SetTrackDescriptions(). If no textual description
is available, the raw index of the track is used.

So VDR just displays what the provider broadcasts - unless, of course,
there is a bug in VDR's code, in which case you're welcome to send a
fix.
