[Cin] Observations using GPU on DNxHD and MPEG proxy while running CinelerraGG

It sounds like from what IgorB is saying, there is nothing wrong with your
Graphics board and I found at least one place on the internet that
indicated it has vdpau capabiities. I simply can not understand why you
still are getting only about 12 frames/sec using OpenGL and why the mpeg
proxy files are not seeing improved frame rate also.

As far as the above, I planned on showing this to GG to get an explanation
of why I too was not getting an improved frames/sec with proxy, BUT he
always makes me prove it to him.  So I had to start Cinelerra from a clean
beginning with nothing set, and then I could not reproduce the 30
frames/sec only and had the full 60 frames/sec in the non-proxy case
already.  I am still trying to determine if I can find the bad case to show
GG but may have to give up.  Phyllis
