does a mac has graphic hardware acceleration?

Hello,

LC 4.6.2, OS X 10.8.2

I have a videoplayer and take snapshots by "export snapshot from rect."-
Before that I set the alwaysBuffer of player "foo" to true.

This works since years, also on current Mountain Lion. Now, I have a
customer with 10.8.2 where the snapshot only has weired pattern of lines and
not the video picture.

I had a similar behavior on some few windows machines and found by incidence
that switching off the hardware acceleration of the graphic adapter solved
it and taking a snaphot worked like a charm again. 

I am not very deep into Macs, I don't even find any graphic adapter setting
in the system settings menue. Where are those hidden? Any other idea, what
could cause such a behavior is appreciated! Perhaps you have experienced
this issue already?

Thank you

Tiemo
