I doubt it's intentional. There are some bugs in the OS X YUV support
(eg crashes on Intel Mac's - i've filed this in bugzilla). I'm not
sure if it's issues with Quicktime (used to do the conversion) or how
SDL is using it.
A quick fix is to put SDL_putenv("SDL_VIDEO_YUV_HWACCEL=0"); at the
start of your program - this forces SDL to use software YUV
