Excuse-me, it has been a week, and nobody seems to care that mplayer is not
able to read a DVD from hard disk.

Nico, maybe you should have a look: that was your patch of May the first
that introduced the bug.

(BTW, current mplayer can not be built with --disable-dvdread-internal.)

I have uploaded a sample in ftp://upload.mplayerhq.hu/MPlayer/incoming : the
pb-bug-mplayer.tar file.

Steps to reproduce:

/tmp/mplayer $ tar xf ~/pb-bug-mplayer.tar
/tmp/mplayer $ ./mplayer -dvd-device dvd dvd://
