Most likely, your problem is your video card.  What kind of card is it?  
Very few video cards in Linux have hardware acceleration in their 
drivers.  If youhave an NVIDIA card, you almost have to use the 
nvidia.com driver.  If you have an ati card, you might be able to get 
away with the X builtin driver, but try the ati.com driver anyway.  If 
you have any other card, it probably isn't being used, so all the work 
is done by the processor.  See if you can use other video programs like 
xine or mplayer without any trouble.  I think most likely its your video 
drivers, though.
