It has nothing to do with the content it is usable with, and everything 
to do with the direction we want to take the presentation of MythTV.  Xv 
has no OSD support to speak of.  Any overlays must be rendered to the 
size of the video, converted to YUV, and baked into the video.  XvMC has 
OSD support, but it is very primitive, and ends up being more limiting 
than Xv.  The fact that XvMC has been unnecessary for any desktop 
processor made in the past five years, and $25 gets you a video card 
plenty capable of handling the OpenGL painter, has just made the 
decision an easier one.
