nVidia binary driver, right?

If this is a seperate backend and frontend, make sure you are using
"streaming" instead of an nfs mount to get the data to the frontend.

You have "use audio as timebase" selected, right?

My 3.0 GHz core 2 is able to handle these streams fine (at 1.0x
playback speed), so there must be some configuration problem.
