Mitchell,

I had a few of the same problems (different cared GeForce 8400 GS)  but was
able to fix all of them.  I am currently (last night) using SVN 19597 and
driver 180.16.  I was not able to get 180.18 working (complains about Load
(Type1) not valid).

I'm using the Advanced 2x HW playback.

The problem I originally had with stuttering playback was actually caused by
audio buffer overruns (improper configured audio).

My CPU was pegged with .21 myth (an no NVPAU) and playback didn't occur.
 Now my CPU is around 9% with trunk and NVPAU.

I would suggest trying the 180.16 driver and the latest trunk.  Seems fairly
stable so far.
