Silverlight supports Windows Media Audio and Video (WMA, VC-1/WMV7-9) and MP3 formats. If you have existing media assets in other formats, you can convert them into a format Silverlight can understand. There are a couple ways to do this.
Use the user interface for granular control over the entire user experience on your media files with support for encoding, enhancement and publishing for Silverlight
Or use the command line interface for batch processing
Choose this when you do not have abundant bandwidth to upload media assets to Silverlight Streaming for encoding or transcoding
Choose this if you have adequate CPU power on your desktop to transcode your assets
Expression Encoder can upload your media files to the Silverlight Streaming service using this plug-in
In the cloud using Silverlight Streaming
The companion service to Silverlight on the cloud at http://silverlight.live.com/ provides transcoding support in the Video Management area
Choose this if you have enough bandwidth to upload (unencoded) media assets to the cloud
Choose this if you do not have adequate CPU power on your desktop machines to efficiently encode/transcode media assets
Choose this if you would like to offload your media hosting to Microsoft's high performance, geo-scale content delivery network (CDN)
PS: my one gripe is that the Silverlight Streaming SDK docs do not explicitly say which file formats it can transcode for you. I know they support .mov, but what about .flv? Hoping they fix this soon.
PPS: tip o' the hat to Angus Logan for his excellent talk at Mix 08 on Windows Live services.
