I've tried different screen resolutions including my monitor's native 1080p. Also, I compared the same videos on an XP Media Center 2005 Edition laptop, in the same players vs. Media Center, and did not experience any difference in color.
Here are links to pictures on Photobucket:

All content in Media Center appears faded, as shown in the above example. All other programs perform as shown in the TotalMedia example.
Any ideas or informations, especially a fix, would be appreciated.
