I've been using "RSS Builder" to create my rss feeds, and they validate fine. But "RSS Builder" doesn't have fields for iTunes or other custom stuff. I have to take the resultant file into an xml editor and manually create the iTunes fields one-at-a-time. I'm willing to do it manually, but updating new iTunes entries manually for each new episode item seems like it would be an error-prone procedure.

My web page is on a server with no Wordpress access. And I want to control my feed, so I'm not interested in using google's Feedburner at this time.

So, I'm Looking for a freeware iTunes rss/xml feed creator/editor. Believe me, I searched, but so far have come up empty-handed. Any suggestions would be appreciated.
