No drawbacks and it's supported on all radeons.  In fact on r5xx and newer
radeons, there is only textured video Xv.  The overlay is still exposed on
chips that support it (r1xx-r4xx) however since some users prefer it and the
overlay filtering is probably better on chips that can't support bicubic
filtering in shaders (r1xx/r2xx chips).  Textured video also has the advantage
of showing up on multiple heads while the overlay can only be sourced to one
crtc at a time.
