Gee, ten minute talks on very specific technical topics... where have I heard that concept before? It really is something technical people need. Here are a bunch from MSDN in the UK along with a pretty nice UI to let you filter by technology, content level, even presenter if that's important to you. They seem to upload more about every other month.
I took a quick listen to "Wrapping Windows APIs with C++/CLI" and I liked it.
