I almost thought buying a video dock for the iPod Nano 3rd gen was a good idea, until I took a look at the formats for the movie rentals on itunes. Everything I saw was widescreen. I have a fullscreen tv with 4:3 aspect ratio and the movies are all formatted in cinematic 2.35:1 or similar. I know that the Nano can "fit" to full screen, but what it appears to do is just zoom in, cropping the rest of the movie. I know that fullscreen movies are not formatted this way, they actually include more height. I'm just saying I would have purchased the video dock and movie rentals if there were fullscreen movies available on itunes.
