It's odd that vlc with "no disc menu" plays it, since that does *not*

But with no menu, VLC plays it in the wrong order.
Best regards,
It really depends on the title you play.
On my Transformers 2 DVD (from Germany), title 10 is the correct one.
Unfortunately, -identify doesn't show the length of all titles anymore,
so one has to run -identify for all titles separately:
for i in `seq 1 99` ; do mplayer dvdnav://$i -frames 0 -identify | grep
ID_LENGTH ; done > log
And the I get the following log file:
ID_LENGTH=0.80
ID_LENGTH=1.20
ID_LENGTH=8656.04
ID_LENGTH=8629.40
ID_LENGTH=9269.76

As you can see, some titles don't even have the correct length (they
play some chapter twice and leave out other chapters):
TITLE 10, CHAPTERS:
00:08:30,00:14:19,00:17:36,00:24:09,00:31:42,00:35:39,00:41:49,00:52:44,01:00:51,01:09:31,01:16:58,01:23:05,01:31:49,01:40:39,01:46:06,01:54:12,02:02:04,02:09:36,02:16:28,02:23:49,02:23:49,
TITLE 12, CHAPTERS:
00:08:30,00:11:16,00:11:30,00:22:25,00:30:54,00:34:11,00:42:18,00:48:12,00:53:39,01:08:39,01:16:12,01:25:02,01:37:04,01:45:10,01:51:18,01:59:09,02:04:58,02:11:50,02:15:47,02:23:07,02:23:08,
etc. But mplayer has major problems playing 14:19 to 17:36 or something,
seeking is impossible there. Using dvd doesn't work at all.
And using -dumpstream, delivers yet another different result. And going
from dvdnav:// via the menu to it is currently the best result. I'm a
bit at a loss to explain why all the different behavior (and what to do
to get a decent playback via direct title access and not having to go
via the menu).
The same is also true for my "The Producers" DVD. Here playing title 1
with dvdnav starts with a clip from another title (but the correct
audio), then the video changes to the correct (and the sync gets
corrected slowly, initial it's 10 seconds or so apart.
After seeking, it gets ok, though... That DVD is from Sony with a
different copy protection scheme. I have the IFO files lying around
somewhere: http://www.roalter.it/dvd/downloads/producers_dvd.tar.gz
That won't work on my True Grit DVD though. I've yet to find out which
of the titles holds the main feature, and dvdnav:// alone doesn't help
either;
There are 99 titles on this DVD.
There are 0 chapters in this DVD title.
There are 1 angles in this DVD title.

Here, funnily enough, it's easier to play the Blu-ray
