im getting the same error with Xine 0.99.2. i am sure i have libdvdcss installed, as well as dvdnav. I could play dvds with with the previous version of xine but now the movies i COULD watch before, wont play. I CAN play dvds with VLC player. Maybe something is up w\ xine?

Umm, highly unlikely you'll see it unless you're in Australia.
It's "The Dream in Athens", distributed by Warner Vision Australia.
It does have some stuff on the cover that might be of use
It was a xmas present so not a very happy xmas for me (but merry xmas to everyone else!)

I just noticed I'm getting a bunch of errors in /var/log/messages when it's trying to play the dvd:
I also noticed I seem to have package for libdvdread and libdvdnav that installed libraries in /usr/lib

Could this be a problem that I have mixed libraries hanging around that's confusing mplayer??
Actually, where does mplayer install its copies of libdvdread etc? I have no clue where they're hiding

TIA

I've spent many hours researching this and, well, I think I found my problem

Seems that my MATSHITADVD-RAM UJ-811, ATAPI CD/DVD-ROM drive has some special capabilities that means that you can only read unencrypted dvds when they are in the same region.

Apparently this is common for several of the Matsushita/Panasonic drives, so if anyone above is using one you may be in the same sad boat that I'm in

Check out the post by Alex Thyl about 3/4 of the way down at rpc1.org.

This would explain my position. I have my drive set at Region 1 and was attempting to play encrypted DVDs from another region. Unfortunately, my Region 1 DVDs are being shipped to me, so I can't reverify if they are actually working at the moment.

Are you serious? That's ridiculous... it means you can't even watch your legally owned copies of commercial DVDs using your own DVD drive that you spent your precious dollars on!

If that's indeed the case, you should write to Panasonic and complain. Jeez, are they MPAA's dog or what?

Seeing as I just relocated from the US to Australia , I'm not very happy

Matsushita and Panasonic are now on my 'banned' list.

I initially had a problem also. I use SimplyMEPIS, and had to install libdvdcvss, using KPackage. Even then, DVDs would play the first chapter, then stop. On the lower left corner of the default 'skin' for xine, there is a button for 'setup' which allowed me to configure many options, including which video driver to use, and I think this was the key. It was set to something (can't remember which), and I changed the setting to "auto". DVDs immediately began to play correctly. This probably won't help you if you are playing from the different region, but hopefully, it will help someone.

hey ladies and gents
had the same problem forever and it seems like so many do. I couldn't figure out what was wrong and kept getting error reading NAV packet sh**.
so i hope that this helps at least one of you.
i am on slack 10.1 but first try
running
$xine -V shm
and after the xine window opens minimize it and go back to the terminal that you the above command has started in and make the window small enough so you will be able to see xine and the term at once when you max xine back.
max zine and click the dvd button
look for some type of error in the term window about
libdvdcss or libdvdread encryption not available or something like (i am truly sorry i can't remember it verbatum) anyways try downloading libdvdcss*.*tar.gz and basically extract, ./configure && make && make install
i believe there is a test in the test dir ./testcss
this should generate something like tada you have libdvdcss and if you have already done this and still it doesn't work go to the next step
download libdvdread and basically do exactly the same as above
extract, ./configure , make, make install
now make sure you reboot because it doesn't work until you reboot.
i wasn't even going to post anything but it sucks not having dvd capability in the 21st century so i wish you all the best of luck

I seem to be having a similar problem with Totem using gstreamer...
I can play the first publisher-logo-thing and then it just goes to 'paused' and I can't get to the menu or skip to the next chapter.

Is this a similar problem, or am I missing something obvious like a n00b?

None of the fixes I've seen have helped, either because they didn't work or because they were for xine and I'm not sure how they'd equate for gstreamer. Can anyone help me out here?

sorry man ,
I am not really familiar w/ gstreamer, but honestly it sounds like it. Totem didn't work until I fixed xine.

Apparently gstreamer just doesn't work with DVD features. Go figure.
I switched to Xine.

I'm having the same problem with some DVDs but not others since my update to Jaunty. I have an LG DVD-Rom, and newer DVDs won't play. They would under intrepid. Threw the same disk in my laptop running Linux Mint and it works, no problems. This won't help many, but the problem to me seems to be Ubuntu Jaunty, and not any of the libraries.

Bug was found in libdvdcss2.

solution: rm -rf ~/.dvdcss

It work also with Add. Sense: Read of scrambled sector without authentication error on new copy-protect DVD.
