Channel 9 video on Project Server 2007 VSTS Connector
If you are interested in how to integrate Team Foundation Server and Project Server 2007, then you need to watch this video over at Channel 9. Lenny Fenster goes through a 40 minute demo of how the connector works.
My biggest problem with the video was how grainy it was. I was unable to make out most of what he was actually doing on the computer. You could get the jist of it by listening to what he was saying, but it would have been nicer to be able to make out what was on the screen.
If you want to learn more about the connector, head over to it's CodePlex site.
