The Drupal Video Planet is a proof-of-concept project I made to demonstrate how to create a section for a site that aggregates relevant videos from across the web, which I hope will get incorporated into the 2.0 version of the Drupal Dojo. This mashup is made possible using the following modules: feedapi, feedapi_mapper, cck, and emfield, with display being handled partially by views and thickbox. You can find instructions on how to do something similar for your site here: http://zivtech.com/node/777 .
