Star Trek: TOS on iTunes

I downloaded a few of the Star Trek episodes that recently went live on the iTunes store.  Last night, I set my TV up with a cheap docking station so that I can play my iPod through my stereo, but I also ran an S-Video line to my TV set so I could watch all the TV shows I've downloaded on a much bigger screen. Surprisingly, the video plays on my TV with amazing clarity.  I figured it would be somewhat distorted, but it looks really nice.
