Plugin to generate RSS feeds from custom post types

Hi

I would like to know if there is any plugin compatible with wpmu that can generate RSS feeds from custom post types.
I tried a plugin Custom Post Type RSS feeds (http://wordpress.org/extend/plugins/custom-post-type-rss-feed/installation/) but it doesnt works..After enabling the plugin for particular site it dissapears from plugins list..

Please advice about any other plugin.

Thanks
