TechEd presentation on Office Open XML available for download
For those of you who weren't able to attend my talk at TechEd 2006 on the file formats, you can actually view it online here: http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?EventID=1032297834&EventCategory=5&culture=en-US&CountryCode=US
The quality of the video isn't great, but it actually does a decent job capturing the demos. The background for the PPT slides doesn't come through too clearly though (but it's not really that big of a deal). You'll also have to deal with my mono-tone presentation style, but hopefully the content helps where I fall short. :-)
It looks like you need to provide a bit of information before you can download the video which is pretty lame, but for now I haven't found a way around that. Maybe I'll just take the video and have them post it up on OpenXMLDeveloper.org site so that you don't have to go through the extra hassle.
