I'm using root
Slackware 10 Xine ( and Totem Movie Player ) KDE 3.2 and Gnome 2.6
Failure to play DVD movies. I get the following error message:
Error reading NAV packet
>> check if another program already uses PCM <<<
snd_pcm_open() failed: -16: Device or resource busy
So I open a terminal and run Top. Top shows that there are no other
programs I have started except the DVD viewer and the volume controler,
and, of course, Top itself.
I tried several different DVDs and the result is the same error.
Has this happened to anyone else using Slackware 10 ?
Has anyone got any idea how to Xine or Totem Movie Player to work?

your problem has nothign whatsoever to do sith dvdnav.. you just can't get access to the sound device. most likely you are running KDE yet trying to use direct OSS output, which won't work. you need to change xine to use arts output in kde.

Problem solved by reading previous error messages
concerning NAV error messages.
1) go to a linux package site and download
libdvdcss
In my case it was libdvdcss-1.2.8-i486-1zeb.tgz
2) Install it using the command installpkg filename.tgz
3) execute the command ldconfig
I also had to edit the /root/.xine/config file so
that audio came from /dev/cdrom, otherwise there
was no sound.
Now it works perfectly, so far.

Ed_999,

I too had the same problem running slackware 10 on my Averatec 5110HX Notebook. Your solution worked perfectly! Thanks for the post.

Thank you ed! I had recently been working on this problem my self. And then I stumbled upon your solution! good job!

Im so glad i found this post, i fixed my problem by telling yum to just install it,

yum install libdvdcss

I restarted Xine and it worked! Woot!

Thanks so much!

Please do not revive dead-and-buried threads. Thank you.
