Session downloads that had audio sync issue are being published back to the web. We've also put together a simple html list for individual file downloads. You can find it at the PDC blog: http://www.microsoftpdc.com/WhatsHappening/Downloadable-Sessions-Available-Now
We'll keep updating the list as the rest of the videos come online. The PDC Downloader automatically picks up these changes so you can continue using it directly as well.
Both of the High formats are 720p. WMV Low is 640x360. MP4 Low is 480x272 - perfect for your Zune HD :)
Thanks Mark. I really appreciate the effort.
Personally I find it a lot easier to have a webpage I can bulk download from using FDM (to take advantage of split downloads), but your Silverlight app is pretty neat!
