Videos appear on certain hubs, which have video links from either youtube or other sites. Most hubbers include video links to help the reader understand the topic better. The videos can be viewed on the hub itself. Just check through various hubs from different hubbers and you will see videos on them as you read from top to bottom. However, please ensure your adobe flash player on your browser is activated and up to date. I do not think having a special part would be a good idea, as the videos do not comprehensively address a certain hub topic on their own.
