I've been researching documentaries on Paganism and I found a couple of interesting videos. YouTube has a couple of shows that National Geographic put together, which are short but interesting:
National Geographic: Wicca
National Geographic: Naked Witchcraft
Then I found a British show that followed the live of five women who study with a wiccan priestess for a month. It has more to do with spellcraft than the philosophy of witchcraft, but it's interesting all the same.

This YouTube link has nothing to do with paganism, but it's a fascinating debate between Islamic preacher Ahmed Deedat and Pentecostal preacher Jimmy Swaggart. They are debating whether the Bible is the holy word of God (Swaggart says yes, Deedat says no). It's really worth listening to, even if only for the pleasure of hearing two great orators go at it.
