This video shows in detail and with annotations how to add plugins as sources in XBoxMediaCenter. With these plugins, you can watch selected media content from the web without browsing the websites with the computer. You browse through the items as if they were on the hard drive of the console. Available plugins include Joox, TVLinks, surfthechannel, seeqpod, powerflv, alpha centauri (german edutainment), stage6, lindenstrasse (german soap), myspace, Apple Movie Trailers, BBC radio, youporn, pronshare, redtube, pornhub, podcasts, and ZDF (german television).
What you need: An old XBox (not 360), a softmod or chip (google for that), XBoxMediaCenter SVN T3CH release (google for that). A remote control for XBMC is also good. Then you can grab a plugin package from http://theendofthelongestline.de/xbox... and install them to your XBMC directory as described in the manual, on the FAQ page and this video.
