Good program for generating iTunes podcast feed?

I'm new to this podcasting thing!

What program (free or $$$) is good for generating good iTunes video podcast feeds, but isn't a "Plain Jane" program. I want customizability, baby! I haven't been able to find one that encompasses user-friendliness, multiple options, and is efficient with iTunes tags. I don't need to have publishing features (since our site security protocols won't allow for that), just as long as I can save to file. I definitely don't want to wade through lines of XML manually coding all day -- my time is better spent producing videos. What do you guys use?

Thanks for any of your suggestions!
