Is there any code for the Savage chipsets at all? I didn't see any in the 
X.org tree when I was looking, but maybe I missed it :-)

Well the only sample driver I have seen is the I810 driver, and it is not 
the best driver because it doesn't do IDCT, just motion compensation. The 
part that wasn't clear to me when I first started this project is that 
the XvMC drivers are client/server like the 3D drivers. There is a small 
component in the X server (surface management mostly) and then a client 
side library that does all the real work.

Also take a look at the reference XvMC player that Mark V. wrote (it is 
on the XFree86 web site still I think). We used that a lot to help get 
our code working.
