Linking to Videos from Visual Studio Help Content
We've recently added links to the How Do I videos that you'll find on the MSDN Developer Centers in Help content related to the videos (and have added links to the Help content from the video landing page.
For example, in the Library topic Overview of LINQ to XML in Visual Basic, You'll find links to two related How Do I videos about LINQ to XML.
We typically add this link at the end of the Introduction section, and add a Play button icon 
to draw your attention to the fact that there's a related video.
On the video landing page, we add a link back to the related Help topics:
We also add links to "video versions of the topic" when a corresponding video exists. These are similar to general How Do I videos, but they directly follow the steps in the Help topic, rather than just being related to the topic. For an example, see Walkthrough: Binding Content Controls to Custom XML Parts.
I hope this makes it easier for you to find related topics and videos.
