I'm utterly disappointed in the lack of screencast GUI content or 2D pixel games. In a playlist designed to be representative of popular Youtube content, this serves to show how video codecs are purposefully neglecting 2D pixel content.

Maybe they just don't want to publicize how poorly DCT-based codecs perform when given sharp edges in brightness and color.
