Questions:

What does M/M Stand for?
How are you measuring the free/available memory?

Info:
I've thought that there was a kernel memory leak with older versions of the
libve driver - which resulted in the system eventually crashing.

However, with the CedarXTestPlayer and the more recent video decode demos
(which I think you have now) I have not been able to reproduce the issue.
