Opera Browser (for Linux) and multimedia
Did you ever try mplayerplug-in with Opera? It’s very bad. Pure X11, no GUI at all. Fortunately there is plugin rewrite under gecko-mediaplayer name which uses new gnome-mplayer tool. Works nicely with GUI under Opera web browser (of course other browsers like Mozilla are supported) ! Available in PLD Th (testing) as rpm packages.
