I ran across a thoroughly engaging article at the Netflix blog that discusses the various encoding techniques they use for delivering "Watch Instantly" content. It sheds light on a number of the issues they face, and some of the decisions they are making. Silverlight is apparently their future player platform of choice, and the article discusses a little bit about why they chose this path. The technical details are appreciated, and it's cool to see them being open like this. Maybe they'll share similar information about other aspects of their business in the future.
