FeedWordPress Mirror Site / Filter Question

Does anyone know of a mirror for feedwordpress.radgeek.com? I’ve been trying to get there for a few days, with no luck (“The connection to the server was reset while the page was loading.”)

I’m trying to insert / embed some code, to handle enclosures, into the post by modifying $content with said code by using the FWP filter syndicated_item_content. I’m not entirely sure that’s the right filter, as it seems to be invoked multiple times during the processing. I’d like to get it right before the $post is inserted into the database, and after all the fields have been filled, specifically wp_postmeta->enclosure.

If anyone has any examples of $content processing, I’d appreciate a look at it.
