Sort of an interesting story on how it came to be that Microsoft Silverlight was chosen to broadcast the Olympics via the series of interconnecting tubes: http://news.cnet.com/8301-13860_3-10003752-56.html?tag=nefd.lede
I'm guessing Silverlight supports our VC-1 codec which rules them all . . . I recently used Expression Encoder 2.0 to encode a 1 hour DVR-MS file (an MPEG 2 stream) from 1.6GB down to 550Mb with litle to no loss in quality - it's amazing . . . it's the mirrors.
