Roxio Buzz has Silverlight Support

Roxio Buzz is an easy-to-use video editor built just for sharing video content, like personal videos or photo slideshows, on the web. The software is great for beginners with features like its one-click delete & restore and one-button editing, which lets you quickly cut and post your video the way you want it. You can also add tags and descriptions before directly uploading your content to the web.

When uploading, Buzz will automatically optimize the video file size to match the website's requirements. The uploading then occurs in the background so you can continue to work. The Roxio software, built on .Net 3.0, works on either Vista or XP, and delivers a rich and streamlined video editing experience. In addition, Roxio Buzz supports Silverlight Streaming. So now, go get your free 4 GB of hosting space for Silverlight, get Buzz, and get uploading! For more info on Roxio Buzz, check out the demo here. (found on Addicted to Digital Media)
