Speaking of HDTV, you more or less need one of those sets for the Apple TV. It's not designed to connect via the older single-lead RCA video cable. You need a TV that takes either the three-lead component cable (the jacks are usually colored red, green and blue) or the all-digital HDMI cable. Newer standard-definition sets may have component inputs, but most TVs out there don't.
It's surprising, then, that videos from Apple's online iTunes store look horrible on an HDTV set. The movies and TV shows have the same nominal resolution as DVDs, but look much blurrier, approaching the look of standard-definition broadcast TV.
To make it worse, these barely watchable movies aren't cheap. "Pirates of the Caribbean: Dead Man's Chest" costs $15 on iTunes, almost as much as the DVD. TV episodes are more reasonably priced, at $2 each.
