Here's a simple way to view the recorded sessions from TechEd US from your browser, even if you didn't attend TechEd. Let's say you browse the breakout session catalog and you see an interesting session like :

 

" ARC313  Patterns for Service-Oriented Architecture
Speaker(s): Ron Jacobs"

 

Simply go to the URL:

http://microsoft.sitestream.com/TechEd2005/[TrackName]/[TrackName][SessionNumber]_files/Default.htm

 

So the recorded session above would be:

http://microsoft.sitestream.com/TechEd2005/ARC/ARC313_files/Default.htm

 

If the session is available, you should be OK.

 

While you're at it - see Scott Hanselman's Code Generation Talk. It's very good.
