Watching HD videos on the new iPhone

I've spent a ton of time admiring the way HD videos look on the new phone. Can anyone recommend some to check out? I've downloaded a few trailers from iTunes, and I feel like I've exhausted what Youtube has to offer.

Any of the Pixar feature films or shorts look great!

Honestly, what I'm looking for is Youtube videos. I don't want to start buying movies from iTunes & filling up the limited space I have.

I think I've used every variation of "HD" in Youtube searches...
