Sure there's other ways
to get bits like Hulu and Netflix on your Windows Media Center and Media Center Extender interface, but since PlayOn
media server's already set up to add streaming video from those and other services like ESPN and YouTube, why not slide them all in at once? If you've already dropped the cash for a PlayOn install or are trying out a demo, the vmcPlayIt add-in serves as a Vista Media Center front end for all those video sources. 32- and 64-bit versions are available for the low low price of free, if this matches your setup it should be worth a try.
