as good as that may have looked...no contest. In fact, the DVD of cars is an edgy, muddy, VHS-esque mess next to the *perfect* 1080p image on the BD. Cars is an A+ hi-def image. Rat is an A++. These two discs set new standards for how good 1080p can look. No kidding.

I'd love to see those discs on that projector!!!
