I'm a DVD kind of guy (people that know me will recognize that as an understatement) and one of the biggest problems with DVDs are that some movies are issued as fullscreen editions, and sometimes are only available fullscreen when the original presentation in the theater was widescreen.
So, I figured I'd do a little evangelism for the cause and post this comparison between the fullscreen version and the widescreen version of the just released Indiana Jones trilogy DVD. I hope this illustration is enough to convince anyone, who didn't already know, that fullscreen is really foolscreen.
