Here some more screenshots:
Xubuntu playing 5 moviesand
MorphOS playing 4 moviesNothing special for most OS's :-P
Edit:
I cheated a little bit on MOS, I paused the movies to take a screenshot because CPU load was 100% with all movies playing. However they played fine.
And in fact there are 5 movies playing but only 4 showing because the first movie was played with overlay and as such only displays a black screen if you take a screenshot. It's hidden behind the tsunami.avi.
