WMV9 HD Render "to bright"

Hello all, just receantly new to vegas video6, and only seem to have
one problem.

After finishing my editing and then rendering the project to WMV9 in
HD I noticed when I play it in windows media player it is to bright!
but if I render in mpg or avi it keeps its original brightness.

But if I play a store bought WMVHD disk.. "Magic of Flight" there is
no issue with brightness.

Anybody else with this issue that found a fix?

Actually I just rendered again in wmv in a lower res 640x480 and that also came out brighter than the original. I thought maybe it was a setting in my window media player so I played the rendered file in my other computer only to see it was to bright on that computer also. Now I can rule out the win media player, it's vegas that is rendering it brighter than it originaly is. Whats the deal, any help?????????

From Sony Admin, using search feature:
Microsoft's DV decoder, which is what gets used in WMP, expands the normal encoded RGB range from 16-235 to 0 - 255 whenever it decodes it for display. While this method is okay (maybe even desirable) for displaying on a computer CRT, it is the wrong behavior for correct video processing. The CCIR 601 standard deals with "blacker than black" and "whiter than white" colors by narrowing the normal RGB range to 16-235, (220 quantization levels). If Vegas expanded the color range in the same way that Microsoft's decoder does it, we'd end up losing vital low and high range information. (e.g. test patterns and overexposed footage). As always, if the final output is intended to be broadcast or played on TV screens, you should always use a good external monitor setup when making color related editing decisions. Gamma response and range even on carefully calibrated computer CRT's are quite different from video monitors and TVs. If your final output format is intended solely for display on computers, you should use the "levels" filter along with the "histogram" view to "normalize" the pixel value range.
