Savage Xv has always been kind of flakey.  you can try adjusting the
Xv attributes to enable  vertical interpolation (use a utility like
xvattr) which may help a bit, however, it causes artifacts for some
users.  Could be a hardware issue, I've never noticed any artifacts on
my savage4 when playing videos fullscreen.
