It looks like VirtualDub will be the easiest to use for color correction with the "curves" filter I've found (it's a VDub filter, which is supposed to be usable in Avisynth, but the 3rd-party instructions don't apply or work with it).

Roughly following the curves of my paint program tests posted earlier, Gradation Curves (v.1.46b) by BBugBunny, A.K.A. Alexander Nagiller, duplicates it's usage and results nicely. The interface makes for easy interactive adjustment -- just like in a paint program:

With the variations of the transfer, this static correction does not produce consistent results ... even within a single shot. For the following video segment test, I tried for an adjustment that would center the variations around the color-corrective "sweet spot". All things considered, it looks pretty good (hope you like it):

Use this .ACV file, colorcorrection.acv (it's a Photoshop format "curves" file), for import into the VDub filter, for the above settings. It can be further tweaked in case of more capture drifting. If ImageShack doesn't like the file being there (not a picture), just manually input these points into Gradation Curves (as pictured above) with the pictured auxiliary setting (i.e. "RGB + R/G/B") and save it:
