mkvmerge, subtitle name

[n2turtles]

Hello,

I've ripped from a DVD
- a video track
- 2 audio track (original and french)
- a subtitle track (french)

I want to merge it into a mkv file
I use this command (using linux)

$ mkvmerge -o myfile.mkv video.avi --language 0:eng audio.en.ogg --language 0:fre audio.fr.ogg subtitle.idx --title "my file"

the 2 audio tracks have right name but "und" for the video (I don't mind) and the subtitle (I mind)
How can I have the language of the subtitle ?

the subtitle was exacted with

mencoder myfile.vob -vobsubout subtitle -vobsuboutindex 0 -sid 1 -o /dev/null -nosound -ovc frameno

Thank you

ok I finally found out

$ mkvmerge -o myfile.mkv video.avi --language 0:eng audio.en.ogg --language 0:fre audio.fr.ogg --language 0:fre subtitle.idx --title "my file"

it was easy

what took me a lot of time to realize is that

$ mkvmerge -o myFile.mkv myFile.avi --language 0:eng myfile.en.ogg --language 0:fre myfile.fr.ogg --language 0:fre myfile.idx --title myfile

procude a strange result with the subtitles (two tracks)
and

$ mkvmerge -o myOtherFile.mkv myfile.avi --language 0:eng myfile.en.ogg --language 0:fre myfile.fr.ogg --language 0:fre myfile.idx --title myfile

is fine
