David,

Below, from your backend log is almost certainly the cause of the 
problem. Playing such large video back via X11 video output will, as the 
third line of the excerpt I've pasted below says, be awfully slow. 
Before going out and buying a new video card (even if it's cheap), I 
would suggest that you see if you can get XV (not XvMC, just Xv) 
working. It may be that the *radeon* driver would give you this where 
RadeonHD and fglrx won't (provided it supports your chipset, of course).

XVideo surface.

output over a network socket.

In any case, good luck with whatever you choose to do.

Cheers,
Jesse
