Matinee: Recording AVIs in Premiere causes 'banding'

I’m recording a bunch of gameplay to AVIs, and I’m finding that all of them look fine when I play the AVIs directly, but when I import them into Premiere, the video it outputs has odd “banding” everywhere. This is 100% consistent for all the videos.

On the other hand, simply re-importing the same AVI into Windows Movie Maker and processing a WMV from that and then importing that WMV into Premiere seems to work around the problem:

Here are the settings I’m using:
