Depends. Especially since OpenGL tends to get better and better, whereas
XV support with some drivers is even deterioration (the number of people
getting only a blue screen instead of a video until they reboot the
computer seems to be ever growing).
Also it can place the subtitles in the border automatically, which is
good for the more lazy people :-).
And the OSD of xv is quality-wise a lot worse, because only the Y part
is changed, so on a green background the OSD will be green as well. And
since the values of the alpha blending aren't clamped you get very funny
effects if you e.g. specify -sub-bg-alpha 200 -sub-bg-color 210.
Though the mmx code should be easy to fix by using paddusb instead of
paddb (does plain MMX support paddusb? Is it slower?).
And last but not least for a developer OpenGL offers much more to play
around with *g*.
