I always associated that "immediately shutting down" when playing video 
thing with either a lack of video RAM on the client or using the wrong 
video drivers.  (Usually vesa when you could force a more appropriate 
choice.)  What kind of video cards do these clients have.

If it was a bandwidth thing it would be more likely to just play really 
slow and/or jerky.  And when mplayer or totem can't find the right codec 
they usually complain about it.

Oh, I should say that I'm far from the most knowledgeable guy on here.  
So YMMVIMHOBBQ and all that.
