How can you fix color banding from VHS video tape in post-processing? Old VHS tapes often have horizontal lines/bands that slowly scroll up or down the video during playback. This video is already on DVD, so I am trying to remove the banding in post-processing.

The Tools I'm using include:
VirtualDub, AviSynth, Premiere Pro CC, Davinci Resolve.

Are there any techniques, plugins or scripts that can help remove this?
Neat Video has been working miracles on footage for us so far, you can give the trial a go! We've never tried it on this specific artifact (that I know of) but it does have features for restoration/archival type damage, and I highly recommend it.
