Some Finnish DVB subtitles are identified as Dutch / Flemish

[otto at kolsi dot fi]

In addition to 'normal' DVB subtitles, YLE in Finland has some programs with some kind of enhanced DVB subtitles. In these, texts are e.g. colour coded according to the speaker.

MythTV identifies these subtitles incorrectly as Dutch; Flemish instead of Finnish. The actual subtitles work well, only the language of the subtitles is incorrect. I've added here logs from the mythfrontend and also from the ProjectX and TSReader Lite (if those are for any help).

Most likely this is not a bug but a designed feature from YLE (Finnish Broadcasting Company)

Basically it says in Finnish that YLE uses "flemish" language code for descriptive finnish subtitles for people with hearing disabilities.

Not a mythtv bug, then.
