That's strange, because I definitely notice tearing with -vo xv but not with
-vo sdl. Besides, sdl also seems to show frames more evenly. I made a vsync
test file with alternating a) black frame, b) black frame with white bar down
the middle.  sdl shows the white bar flickering regularly, while with xv the
display is quite irregularly (and sometimes teared). gl is regular but teared.

Perhaps SDL uses XV in another way than -vo xv, if it could be made to work the
same, that would be perfect.

It is enabled, but not used, I think. I'll try disabling later.
