I have a color problem with Hauppage PVR USB2.

THe Color default setting is too bright for capturing, so I reduced the brightness level to the closest to the original. But at this setting, my monitor displays the image a little too dark for my liking. The problem is that WinTV2000 is not capable of storing several Color Profile like Winfast PVR software, ex, for viewing on monitor & recording. This creates a problem for me because I can not create a setting that will look good both in my monitor & my capture. So far, the only thing I can do , is to take note of each setting for viewing & recording, and manually adjust them each time. This is not practical at all.
Is there any possible solution ?
Doesn't anyone have similar problem with the color adjustment ?

I read in the forum that I can sharpen the picture with registry tweak,
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Globespan\Parameters\ivac15\Driver]
"SharpnessValue"=dword:00000007

But frankly, I don't see any effect on the picture, nor my recording. Is this tweaking also applicable to PVR USB2 ?
Is it supposed to bring changes on both monitor & capture at the same time ?

In Hauppage Tweak Tool, the 150/500 Tab ((Brightness, Contrast, Saturation, Hue, Sharpness) seems to have option to set "Capture Filter" & WinTV2000 independantly.

What do you think about the image ? Is it really that bad ?
I find it too dark, especially in dark scene, it can get really fuzzy & hard to see.
