I am confused here. I have a fresh F8 install on a Celeron 1.8 based system which declines to play dvds placed into the system dvd drive. The livna repository is also installed by rpm, and provides the multimedia software. Running mplayer from the command line gives an error message from libdvdread (think I got that spelled right) with an assertion failure. gxine, xine, vlc, and (of course) Totem all fail to play also.
What irritates me is that a different machine with F8 runs the dvd playback just fine.
Any bright ideas of where to start looking (systematically looking this time).
Thanks for the assistance
