Here is a plugin for yahoo videos.
http://xbmc-scripting.googlecode.com/svn...Plugin.zip
I limited the search results to AOL, Yahoo and Youtube. I also add the word "music" to the query, so test it and let me know how it works. If you know of any other sites that are partners with Yahoo, then those can be added.
This is a plugin, so put it in q:\plugins\video, then if you have a newer version of xbmc, go to library view and video plugins, or you can add source video plugin from files view.
I'll consider suggestions. There is rough download code in now, but it's not activated. That may be a future update.
I included one preset, so you can see how it works.
When you do a search, you have the option of saving that search as a preset.
Also, if you go to sortby and choose studio, the host site will display so you can see if it's a youtube, yahoo or aol video.
