BestQuality enabled, but brightness and contrast ineffective

[totalv]

I've tried to adjust brightness, with like +/-50 to see the effect, but nothing changed visually!!

* Hardware Acceleration Enabled (nVidia PureVideo)

Works perfectly fine for me. But you could have video overlay enabled. In your nVidia control panel go to:
"Adjust Video Image settings". And make sure the "Use video player settings" is set to both options.

(On Windows 7, just type nVidia in the start menu and the nVidia control panel should appear).

Hope that helps

We have tested this on the same PC spec as yours and works fine.
Please make sure like mattisdada said to check settings in grpahics card control panel.

thanks guys, that did the trick.

Or I could force video overlay in settings, but that disables Windows Aero effect.
