I you media setting for internal video playback what arguments do you us for VDPAU playback?
I think the default is some thing like:
mplayer -fs -zoom -quiet -vo xv %s
I have tried
mplayer -fs -zoom -quiet -vo vdpau %s
but was wondering if there are any more tricks, options, or tweeks.
will -vo vdpau,colorspace=0 correct for proper studio levels?

In Utilities/settup -> setup -> Media Settings -> Videos Settings -> Player Settings
The correct arguments/options for VDPAU playback of your Mpeg1 or 2 videos are:
mplayer -fs -zoom -quiet -vo vdpau:deint=4:colorspace=0 -vc ffmpeg12vdpau
for my nvidia 9500 GT
Where deint=4 is similar to temporal 2x deinterlacing (deint should be reduced to 3 or less on 9400 gt or less powerful graphics cards). Colorspace=0 (jyavenard build) alows for the detection of correct studio color levels on a TV that doesn't have a DVI, Sub-D input, or support computer monitor color levels over HDMI
The -vc or video codec will have to be changed if you want vdpau acceleration of codecs other than Mpeg 1 or 2.
See man mplayer
(-vc ffmpeg12vdpau, ffwmv3vdpau, ffvc1vdpau or ffh264vdpau)
If you have a 9600 GT, 220 GT, or better you can do all the bells and wistles such as
mplayer -fs -zoom -quiet -vo vdpau:sharpen=.5:denoise=1:deint=4:chroma-deint:pullup:colorspace=0 -vc ffmpeg12vdpau
[The above section with a smiley face should read as "chroma-deint : pullup" without the spaces. I don't know how to turn off emotocons.]
Which is the similar to Advanced 2x Deintelacing with noise reduction and image sharpening controls
sharpen=<-1 to 1> example -> :sharpen=-.25 will soften the image and sharpen=.44 will sharpen the image
denoise can be a positive number from 0 to 1 and allows for adjustable noise reduction
