Dynamically Updating YouTube Videos On Your Website
I've just added a YouTube plugin to my RSS to HTML converter script, CaRP.
Using the new plugin, you can display YouTube videos on your website using their preconfigured RSS feeds (for example, recently added, top rated, most viewed, etc.), or you can get a feed for any tag or YouTube user by following the instructions shown on the page linked to above.
For example, the address for the feed for my videos is feed://www.youtube.com/rss/user/GeckoTribe/videos.rss
When the feed you're displaying updates, the videos displayed on your website will be updated automatically too.
