Ubuntu 10.10: DVD Playback Stopped Working After The Upgrade

[Steve]

Hi;

I upgraded from Ubuntu 10.04 to 10.10.

I could play a particular DVD without problems before the upgrade.
After the upgrade, totem just sits there and outputs these messages to
a terminal.  Youtube works fine.

$ totem

Any ideas what I need to do to get DVD playback working again.
