Sorry for hijacking the thread. I'd like some hints on how to debug playback
with a DVD here. The strange thing is, that the DVD plays fine with your patch,
however, without it, I can't seem to find any english subtitles at all. :) The DVD's
menu has 3 language choices at start, and if I click english, it works quite well,
a few subtitles at the start are lost, but after that it works.

With regular dvd://, trying -sid from 1 to about 20 yields no english subtitles.
I was wondering where to start adding printf's and similar, in order to figure
out what subtitlte (is that spu?) stream MPlayer is playing with dvdnav://.

A two year old version of xine, which has dvd menu support, does not seem
to be able to find the english subs either. There's something strange about
the disc.

Is it possible to make DVD which wouldn't show subtitles with regular dvd://
playback, btw?

Anyway, any hints where to start looking would be appreciated.
