Hmmm, which Nvidia drivers are you using?  IIRC, 0.16 introduced a new 
video sync method for playback, based on OpenGL, for > 6611 drivers.  
With the old 4363 driver it used the /dev/nvidia method, which no 
longer works with later drivers.  I'm not saying this code is buggy, 
but it may be exposing some other problem in your system.  In the 
Nvidia/Linux forum, lots of folks have reported problems (lock-ups, "X 
using 90% of CPU", etc) with the Nvidia linux drivers, especially when 
OpenGL is used.

Also, have you tried testing video playback with other programs?  Try 
the following:

mplayer -vo xv <file>
mplayer -vo gl <file>
mplayer -vo gl2 <file>

Do any of those cause problems?  If so, suspect your video card or 
driver.  You might also want to physically inspect your card.  I have a 
LeadTek GF4 MX 420, and recently my display starting locking up with I 
start X.  After much Googling, I took a look at the card itself and 
discovered that the chip fan had stopped working & that the capacitors 
were bulging.  I'm in the process of getting the card RMA'd.
