The title says it all. I've done some searching but not stumbled upon something useful.
When I insert a disk Totem starts, and the movie on the disk begins to play, but not smoth - it stops and restarts several times. After a minute or two it freezes so hard I had to use the reset button. Strangely enough I could use Alt+F1 and Alt+F2 but could not "Quit" and turn off .
Mplayer compains that it could not open the DVD player
"Error Failed to open dvd://1" I'd expect /dev/hdd or /media/cdrom1 but that might just be ignorance
Could be the disk - I'll have to find another one - not a big movie fan
//edit// Did not find an advice in another post to change the preferences in Mplayer to use xv. It now plays a bit longer that totem and then locks up hard, but I can use the rest of the system.

I've managed to find out a bit more. One DVD (with Joe Labero, probably not Contentscrambled) plays just fine, but the one that doesn't play may have some problems with (the dreaded) css.
If I start totem from a terminal and then play I get the following output in the terminal:

libdvdcss is installed as far as I can see (and could hardly have been used if not).
/home/mats/.dvdnav/.map does not exist as stated above.
That dvd works ok in a DVD player in a TV set.
This seems to be a common problem, I've seen a lot of posts in the ubuntu forums about this, sadly none that helps me. I can live without DVD movies, but I definitely want things to work

OK - the movie I can't play will not play in Win XP (Power DVD) either. Another movie plays just fine in Totem, all disks and the player are zone 2, so this might be just one of those things...

My "original problem" was obviously hardware. I've played the movie w/o problems in the DVD burner I just installed
