Vimeo! (Score 1)

Vimeo is really nice. The UI is great, the video quality's good, and they even put a link on the page to download the original file format you uploaded. I'd recommend using Vimeo as the primary source, uploading to Youtube just because people are on there and searching, and also maybe sticking an iPod version and/or high quality xvid copy on Amazon S3. That should cover most bases.
