High res

It might not seem like much, but the difference between 480p and 720p is pretty striking. That is, old TVs broadcast 480 lines of resolution, and many new TVs produce 720 lines. If you want to see the difference between these two resolutions, go here and hover your cursor over the screen captures. WARNING: Seeing Martin Lawrence and Tim Allen in high definition may cause seizures, death, or an overwhelming feeling of hilarity.
