I've had success with 'xine' 'kmplayer' (very slow) 'mplayer' (ok but full screen) and 'kaffeine"
Yes, but those apps are not default apps. Kaboodle is the only base app that plays videos.
Xine is indeed a dependency for several Trinity apps, but all of those apps are not base installation apps, like amarok, kaffeine, kmplayer, etc.
