Of course! I'm a lawyer. We *ALWAYS* have ideas. How many can you afford?
Seriously, however, what else is in your xorg.conf? Do you have:
AIUI you properly should not need those: the driver is supposed to do it
Once that is on place, do a cold boot and look through
/var/log/Xorg.0.log. You *should* see a section like:
(II) LoadModule: "extmod"
(II) Loading /usr/lib/xorg/modules/extensions//libextmod.so
(II) Module extmod: vendor="X.Org Foundation"
compiled for 1.3.0, module version = 1.0.0
Module class: X.Org Server Extension
ABI class: X.Org Server Extension, version 0.3
(II) Loading extension SHAPE
(II) Loading extension MIT-SUNDRY-NONSTANDARD
(II) Loading extension BIG-REQUESTS
(II) Loading extension SYNC
(II) Loading extension MIT-SCREEN-SAVER
(II) Loading extension XC-MISC
(II) Loading extension XFree86-VidModeExtension
(II) Loading extension XFree86-Misc
(II) Loading extension XFree86-DGA
(II) Loading extension DPMS
(II) Loading extension TOG-CUP
(II) Loading extension Extended-Visual-Information
(II) Loading extension XVideo
(II) Loading extension XVideo-MotionCompensation
(II) Loading extension X-Resource
before it loads the nvidia driver.
Regarding using mplayer, what happens if you use just:
mplayer -vo xvmc file,mpg
I have had some weird results with the latest Intel driver, where it
plays standard def files withour problem, ONLY if I do not add the usual
-vc ffmpeg12mc filter. No, I have no idea why.
