There are a few limitations to the supportability of the Windows Media Encoder 9 series application and SDK. Microsoft has extended support for this product for the next year or so. Hopefully if you are reading this you are aware of the next generation of the Encoder named the Expression Encoder. We are now on version 2 of the Expression Encoder and I would highly recommend that you take a look at it if you haven’t already. We still have a large WM Encoder user base and the Expression Encoder is just starting to come into its own.
