Recently, I did a session on Advanced .NET Debugging at the Atlanta Microsoft office and it was recorded for posterity. You can catch the three part video up on Channel 9, here, here and here. Unfortunately, the sound isn't the best in the world, but it's still understandable. Fortunately, all the people in the audience laughed at all my bad jokes. Maybe that's because I paid all 150 of them $50 each to laugh no matter what.

Hope the video helps you out!
