I'm trying to play DVD's on my laptop using Xine. I'm testing with three different commercial DVD's; one works great (menus and all), one plays the FBI warning then stops with an error, a third doesn't work at all (hit play, get an error!). Here is the error those latter DVD's give me:

"The source can't be read. Maybe you don't have enough rights for this, or source doesn't contain data (e.g. not disc in drive). (Error reading NAV packet.)"

...clicking on the "More..." button reveals a few more messages. Most of these seem benign, but a series of messages say:

"audio_decoder: error, unknown buffer type: 04000000" (the number tends to change)

Based upon other suggestions from this forum and others regarding similar problems, I've taken the following steps:

- Tried xine-check from the command line. Everything returns "good". I've included the output at the bottom if it is of interest.
- I've loaded the DVD libraries:
libdvdcss
libdvdnav
libdvdplay
libdvdread
(I've even loaded the development packages like libdvdcss-devel, etc)
- I tried Mplayer: It has the same results (plays one of my DVD's but not the others)
- I tried Ogle. It plays only the audio of my first DVD and just shuts itself down when trying to play the other two.
- I checked the permissions on my dvd device:
/dev/hdc: brw-r--r--
/dev/dvd (which is linked to /dev/hdc): lrwxrwxrwx
/dev/cdrom (which is also linked to /dev/hdc): lrwxrwxrwx

Any thoughts as to why I would be having these issues?
Thanks, BS

What do the permissions of the .vob files look like? Could it be that they are too stringent? Don't know if you have but try playing them as root.

I use Totem, and I have the libdvdread and libdvdcss libraries installed, and I occasionally have problems, especially when I'm trying to do too much in a session. One little trick I have done to make it straighten up and fly right is open a term window, su root, ldconfig, exit, THEN start Totem and it works fine. Still trying to figure out how and why my installations are losing track of their shared libraries. (I use both Slackware 10.0 and Mandrake 10.x and they both occasionally do it to me.)

Hope this helps.

So I tried your suggestions. I ran Xine as root and got the same results (1 out of 3 dvd's work). The permissions on the dvd's show read for everything.

I also tried loading and running Totem with the same results. The error I get with Totem is:

An error occured
The movie 'Error reading NAV packet.' could not be read..

(strange - I've never heard of a movie called 'Error reading NAV packet' and I'm not sure I'd want to watch one either!)

Any other suggestions out there?

This may be of some help to someone. I figured out how to get some feedback by launching the program from the command line using:

$xine --verbose

Knock, Knock... Anyone home?

Was this prob ever solved?

I have now got the same message coming up under latest xine.

Stops the DVD playing halfway through the animated menu. Cannot progress.

Nope... Still waiting and wondering if anyone out there has any thoughts.

Many of the DVD playback errors can be solved by following the directions on this page. Hope this helps.

Been there, done that. But thanks for your input.

I'm betting you're having issues with macrovision encoded disks....

>_<

I can't play DVDs at all. I'm able to watch the "New Line Home Entertainment" opener for American History X, and that's it thus far. The majority of my problems are documented in this thread: http://www.linuxquestions.org/questi...hreadid=256985.

Now, what is this Macrovision, naraht? Are many DVDs encoded in such a manner?

I am a linux "newbie" some might say. I run amd64 3000, and spent several hours (days even) trying to get my dam dvd player to work. I really wanted to start using linux permanently, but without dvd movies on my pc well ..... I run mandrake 10. I finally figured out how to get it to work. I had downloaded xine all the xine options from my auto update feature (just basic xine stuff). I then installed 2 rpms from the ogle website which made all the difference (at least one did?). libdvdcss for x_86 from the "freshrpm" link. Next, libdvdread x_86 from the "freshrpm" link. After installing both of these my "Matrix" movie came to life. The exact names were libdvdcss-1.2.8-4.1.fc3.fr.x86_64.rpm, libdvdread-0.9.4-5.1.fc3.fr.x86_64.rpm. These plugins are currently not included in the dvd software packages due to current legal debates. I honestly hope this helps someone. Long live linux.

Try setting permissions on your dvd player. Find out where /dev/dvd is linked to (it will be /dev/hdX where X is a-z depending on how many ide devices you have). Then switch to root (or use sudo) and change the permissons to 1777 (chmod 1777 /dev/hdX, for example).

Try that and see if you don't have better success.

Blessings,
Curuin

if you are running an rpm based distro, istall libdvdcss, win32 codecs, xine-lib (libxine) and xine-ui from the xine nightly website. All dvd's should be able to play fine (ell hopefully). By the way uninstall any xine or libdvdcss packages first.
