I also can't play any video format at any video player (totem, kaffeine, mplayer, vlc, miro...). The outputs are the same presented by IcedEarth.
Workaround to get it working: open gstreamer-properties. Then, Video tab, Default Output section. Change the Plugin from "Autodetect" to "X Window System (No Xv)" and close. This way, totem will play any video format, but the other players still not working. # uname -a Linux laptop 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux # lspci 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) # dpkg -l | grep xorg-video-intel ii xserver-xorg-video-intel 2:2.6.3-0ubuntu9 X.Org X server -- Intel i8xx, i9xx display driver I just updated my system (aptitude update & full-upgrade).
