Uploading videos to itunes is not easy

This afternoon I have been mostly trying to get our videos onto itunes. We're very big on YouTube, and itunes is very popular, so we'd like to be on there. Is that too much to ask?

It would seem it is. The explanation of How To seems simple enough. You get an RSS feed of your videos, and itunes will take that. Only it won't. None of the following RSS feeds works on itunes. I am mostly told there are "no episodes" in the feed, or that there is something else wrong with them. Does anyone out there know, having looked at these RSS feeds, what I can possibly do to get my videos on YouTube.

This has taken all afternoon to absolutely no avail. Help!
