where FILENAME is any movie which is supported by ubuntu codecs (if you want to have more codecs, you have to look for unofficial packages, e.g. medibuntu).
To test if your file is working _without_ xv accelerated video, just do
mplayer -vo x11 FILENAME (if your system is fast enough, this should also work during 3d effects, while with xv you'll see a blue window when rotating cube, zooming etc.)
ld2ndR: install mplayer and run
mplayer -vo xv FILENAME
