joomla allvideos rss feed script needed

We are using joomla 1.5 and have a separate site for video sharing using a video sharing script called clipshare. We want to be able to have an RSS feed from our video sharing site (clipshare) to our Joomla site, showing for example the 6 most viewed or latest videos through a media player on our joomla site using for example the Allvideos plug-in. The project is to write the code for the RSS feed.
