wordpress video sitemap modification

I have an existing video sitemap plugin and would like to modify it so it works with 3rd party videos embedded like youtube, vimeo, etc. Also it needs to work with 3rd plugins that host videos from sites like youtube, vimeo, etc. If you are familiar with wordpress plugin and can modify then this is easy for you. It is also an on going project that will need support so extra work will be there. here is an example of the video sitemap in action; networkonlinesecrets [dot] com/[login to view URL] I will provide a copy to the winning bidder to work on.
