Real-World Analysis and Optimization of XNA Framework Games on Windows Phone 7

This is a horrible recording. The audio cuts out every five seconds or so. The constant interruptions make it very difficult to concentrate on what Herb is saying.
Videos are not working: MP4 high and low doesn't work at all. WMF's audio is stuttering.
(Btw.: This form does not handle german umlauts in the name field.)
Where is the original talk? The editing is horrible.
The audio is horrible. Why do not you fix it and repost it again? Thank you.
