Well, as the -v output writes:
[mkv] | + a track...
[mkv] |  + Track number: 4
[mkv] |  + Track type: Subtitle
[mkv] |  + Default flag: 1
[mkv] |  + Codec ID: S_VOBSUB
[mkv] |  + CodecPrivate, length 167
[mkv] |  + Language: cze
[mkv] |  + Name: Czech subtitles

The "Default flag" thing indicates that whoever created that file wanted
the subtitles to be on by default, so MPlayer behaves right in principle.
I guess maybe mkvmerge could be used to change that setting.
Apart from that, maybe there should be a way to ignore this, though the
question then is: how? Reusing the -noautosub for this? Or using -nosub
(like -nosound) or?
