Foreign PGS subs missing language flag

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Select any foreign (i.e. not English) subtitle in a M2TS.
2. Select mux all PGS subtitles.
3. Do a remux.

What is the expected output? What do you see instead?
Only English PGS subs will have a language flag. IDX/SUB subtitles will have 
language flag on all subtitles.
The subtitles without language flag will still work but it's annoying to not 
have a language flag, instead it says "Undetermined/Unknown" in players.

What version of the product are you using? On what operating system?
-blurip_svn142 & blurip051
-Win7

Only subtitles/audio tracks with a language tag that is in preferred language 
list will get a language tag in mkv.
Try to add the missing languages in the preferred subtitles language list.
I will try to add something to set the language for tracks with no preferred 
language.

Ah ok, I thought the "preferred language list" was just for selecting what 
languages will be auto selected when loading the M2TS. Specially since all 
IDX/SUB subtitles get a langauge flag.

Yes, the preferred language list is for auto select. But it is also used to get 
the language iso tag (e.g. 'en' or 'de').
The latest commit includes a search for the iso tag for any language.
Will upload a new svn build later.

I did a test. "Modern Greek" doesn't seem to get a language flag.

It worked for all subtitle tracks. Track 4 & 5 are english - this isn't 
displayed in MediaInfo.

Maybe you can send me the complete log?

"Track 4 & 5 are english - this isn't displayed in MediaInfo."
What do you mean? Do they have a language flag in players then? English subs 
are displayed in my MediaInfo at least.

Here's a remux with "Modern Greek" missing the language flag. Every other 
language seems to work so far.

A bit offtopic, though I don't get why those forced subs are created (aka 
extracted from the original sub I guess). The Spanish sub only contains "FIN" 
at the end, the French one contains a couple more lines.

I did two more remuxes and this time the English sub had no language flag in 
MediaInfo, it showed up fine as "English" sub in players though.
