Hulu is offering a handful of HD video samples for its beta testers, but you have to have big pipes to see it: 2.5 mbps or higher with a 3 GHz or faster PC. “The quality of these samples is certainly impressive,” writes Mark Hendrickson in Techcrunch. Meanwhile, iTunes has added HD video podcasts over the last several weeks. I’ve been watching Diggnation HD on my Apple TV, and it’s very clear (although not like watching a HD channel on TV, mind you.)
