[MPlayer-users] DVD languages show as unknow aid: 128

Well, I can tell you where it comes from (though I'm not completely sure
whether it comes from video_ts.ifo or vts_01_0.ifo): Do
hexdump -C -s 0x200 -n 32 video_ts/vts_01_0.ifo

This is what I get with a working DVD:
000200  53 00 00 08 04 c5 65 6e  00 00 00 00 04 c1 66 72 |S.....en......fr|
000210  00 00 00 00 04 c1 64 65  00 00 00 00 04 c1 69 74 |......de......it|

lang_type is the bits number 3 and 4 from the bytes with that value 04
in that dump.
If you want to know what it is supposed to mean, I guess you'd have to
refer to the specification for ifo files, but I expect that the tool you
used to create the DVD is one of the many that don't care about the
standard... Or of course MPlayer might be wrong ;-)
