where to find media feeds

Here are a couple resources to help discover media content distributed through RSS feeds. Anybody know of more resources like these? Any way that our videoblogs could ping a server to alert services like these (and those that are around the corner) know that we've just published a new video?

Also, a nice article from O'Reilly on creating soundbytes from longer audio and podcasts… wonder if something like this would work for video?
