Raymond, do you have any first-hand experience with OpenGL on Intel's
HD Graphics/2000/3000? I wrote about my experience using OpenGL on an
i3-540 here:
http://www.gossamer-threads.com/lists/mythtv/users/487654#487654. In
short, it was unusable. It was fine with xv-blit, but its scaling of
the OSD to the source material was a deal breaker for me, so I ended
up adding an nvidia card. I don't think I've seen any positive reports
about OpenGL on HD Graphics, although it's certainly possible that
there have been some and I've just missed them.
