The audio issues are minor and doesn't really distracted too much from a great conversation on UX and Xaml Data templates. Billy is great in the video with sharing his thoughts and experience. The explanation on the user's need for excel like grid for displaying data was good.
Jack beat me in writing about the same issue that I had with this session video. The sessions has a ton of great content but you could hardly see the star of the show which is the code. I found it difficult to follow Jeffery simple because I couldn't make out what was happening in the code window. If the powers at Channel 9 could redo this video to showcase the code in HD full screen that would be super awesome.
If possible Jeffery if you could post where we can get the source code we would be super grateful
