Yeah, each of those resizes exhibit the same green tint.
I'm hesitant to think the green shift is just the effect of compressing the image. Keep in mind, the AVI I included earlier is the source file. The file named "NotResized.mp4" is still a compressed version of the file, just not resized. If it were the compression causing it, wouldn't we see it on the NotResized version as well? The NotResized file does not show the green tint. It appears identically to the source AVI. The green tinting only occurs when you resize the video, as demonstrated in the Resized.mp4 file.
If you're just talking about horizontal compression, rather than just file compression, I don't think that's it either. For example, if you play NotResized.mp4 in MPC-HC, and set the Video Frame Aspect Ratio to 4:3 (horizontally compressing/squishing the image), you'll see the green tint does not occur. It still appears identically to the source AVI, with no green tinting. See the screenshots below...

Thanks again. Hopefully we'll be able to get to the bottom of this!
