Where can I find a thorough DirectShow tutorial?

Question

I've read through the MSDN documentation on DirectShow and it's still confusing. I feel like I need more context for what the objects are: Graphs, Pins, Filters...etc. A Google search doesn't give me much to work with. What do I need to grok DirectShow?

EDIT: The wikipedia page on DirectShow does a pretty good job.

Answer 1

MSDN Magazine has a nice article in their July 2002 Issue: DirectShow: Core Media Technology in Windows XP Empowers You to Create Custom Audio/Video Processing Components

Pascal Mignot from Université de Reims has gathered information from MSDN documentation into a single document, which gives a nice overview.

Answer 2

Also, there is a very good book on DirectShow.
