ok, I see you are using the "ati" driver, so the vendor string will read 
mesa.  You check it by typing glxinfo at a command prompt.
At any rate, it doesn't matter since you're using "ati"; if I'm not 
mistaken xv should still work.
I think all you have to do is manually add in the line
Option "xv"
or something to that effect.  I never used "ati" so I can't be sure; 
might want to try googling something like
"use xv with 'ati' driver in X" or similar.  I know that for me, when I 
was using "radeon", xv was not working by default.
