If you visit youtube.com, right-click on a YouTube video and you'll find a new option: "show video info". YouTube displays a lot of information about the current video: resolution, bitrate, frame rate, file size, the number of dropped frames, volume. There's also an option to copy information useful for debugging.
In other YouTube news, Chad Hurley posts that the site serves more than one billion videos a day. "Three years after the acquisition, our platform and our business continue to grow and evolve. We are still committed to the same principles that informed the site early on, but we know things have changed. As bandwidth has increased, so has our video quality. (...) We're working hard to keep up with the fast pace of technology to bring you everything you would expect from the world's largest video site: better quality; a full spectrum of choices and tools for users, partners and advertisers; and ways to make the YouTube experience your own anywhere, anytime."
