If you’re like me and have an old laptop with an ancient video card you may find Movie Player quitting even with a new installation of Karmic.
All you need to do is disable Xv in your video players and use X11 instead. Its a bug in older GPU drivers causing this.
To do this for each of the main media players:
(helpful howto taken from here(clicky) (http://ubuntuforums.org/archive/index.php/t-513822.html))
For Totem with the gstreamer backend (totem-gstreamer) open a terminal and type gstreamer-properties
Then click the Video tab and under Default Output select X Window System (No Xv) for the plugin. Then restart Totem. This will work for any video application that uses gstreamer as it’s video backend.
If you use MPlayer (GMplayer) right-click on the screen and select Preferences then select the Video tab and under Available Drivers select X11 (XImage/Shm)
then restart MPlayer. The issue here is that it won’t go fullscreen with the video. I suggest using VLC or totem-gstreamer.
If you use Xine then go to File -> Configure -> Preferences.
(make sure under experience_level you select Master Of The Known Universe)
You will get a tab at the top for Video. Under driver select xshm. Then restart Xine. This also works if you are using the totem-xine backend. Just run gxine at the terminal and follow the steps.
For VLC select Settings -> Preferences then in the bottom-right of the window check the Advanced Options box. Then expand the Video item on the left and select Output modules. Then in the list on the right for Video output module change it to X11 video output. Then restart VLC
