[MPlayer-users] DVD Subtitle issue

This is not limited to mplayer, but should rather affect DVDAuthor as 
well, as the spuunmux program does not what it should do -- at least on 
one file I encountered so far.

I have the streamdump of the german Moulin Rouge DVD, which prints on

mplayer -v stream.dump

system stream synced at 0xD (13)!
==> Found video stream: 0
==> Found audio stream: 129
==> Found audio stream: 128
==> Found audio stream: 133
==> Found audio stream: 132
==> Found audio stream: 131
==> Found subtitle: 3
==> Found audio stream: 138
==> Found subtitle: 2
==> Found subtitle: 1
==> Found subtitle: 0
MPEG-PS file format detected.

and later on (when playing around 15 seconds)
==> Found subtitle: 4 0%  0.0% 0 0
V:  17.0 425/425  0%  0%  0.0% 0 0

Now, when I play this stream with -sid 0, 1, 2, or 3, I don't get any 
subtitles at all. If I play it with -sid 4, I see the subtitles for 
stream #0 (english).

When I demux the subtitles with spuunmux -s 4, I get the stream #4 
(which is the subtitles for the director's commentary).

so there's one common thing with mplayer and spuunmux as they both play 
only subtitle streams which are found only later in the stream, but not 
if they're on just at the beginning (all the other DVDs I checked don't 
have any subtitles at all at the very beginning).

There's still on thing differing: the streams which come in later (as 
does stream #4 on my example) default to stream #0 on mplayer and the 
real stream #4 on spuunmux...

Any suggestions about how this can be corrected? It would be more 
pressing on spuunmux, but maybe if there's a fix for this with mplayer 
(so that the subtitles show up after all), I can apply something similar 
to spuunmux.

something other: the german Star Wars DVDs have multi-angle support, and 
it seems the subtitles show up also doubled, so there should be 7 
subtitle tracks (IIRC) at all, but mplayer finds 14 of 'em. And playing 
directly from DVD won't produce acceptable results, as with the 
subtitles above, the exact subtitle specified by -sid is not always 
played (on the Star Wars DVDs it plays the subtitles for the hearing 
impaired when I want the subtitles for the alien speeches only). Ripping 
it (and getting rid of the multiangle btw.) solves the problem, I can 
access all subtitle tracks as intended... ?-)
