[opensuse] Firefox 3.0.5 and mplayerplug-in 3.55

(opensuse 11.1) Is anyone else having problems using mplayerplug-in with Firefox? I've indicated mplayerplug-in in the Firefox applications preferences but when I try to play a video, I get a dialog box asking me if I want to open with Banshee or other... If I go to other, I get pointed to my home folder. (Streaming video works just fine.) Any suggestions appreciated. -- Don Henson
