A new version of media center software that adds support for Netflix Watch Instantly streaming movies has been released by Boxee.

Boxee’s new release includes the option to both browse and search through Netflix’s library. Boxee works on any Intel-Mac or Linux PC. As of now Boxee’s is not available for Windows.

Netflix streaming is not yet available for the AppleTV version of Boxee. The reason for this is the main reason is that Microsoft Silverlight, which is what Netflix uses as a delivery method for its streaming content, has hardware requirements roughly double that of the processor inside the AppleTV. Silverlight requires a 1.83GHz dual-core Intel processor, while the AppleTV only sports a 1GHz “Crofton” processor–a derivative of the Pentium M.

Boxee also have MTV to pop up music videos for any songs in your library that it can match. There’s also support for YouTube videos that have been encoded in h.264, and new player interfaces for Hulu, CNN, Picasa, YouTube, and Flickr.

Existing Boxee users should get an update notice when firing up the app later Thursday. The service remains in private alpha.
