This is not an advantage.  This is the user running the antiquated Xv
video
renderer, rather than the OpenGL renderer. Anyone with sufficient GPU
power
should be using the OpenGL renderer which doesn't suffer from that issue.
This is part of the reason XBMC already has, and we were considering,
dropping
the software painter and Xv renderer.

Could you give some specific examples of this?  I've not heard of any such
disks.  I would more guess your decoding profile was set to "Max CPUs" of
1,
preventing use of multi-threaded decoding.
