Is there an easy way to convert movies/videos purchased through iTunes to MP4? I have a couple that I would like to be able to watch on my tablet, but it plays only MP4 format for videos. I did a search, but didn't find anything on the site about this. I also tried googling, but the results on the first page were all pointing to software I'd need to pay tons of money to get. That's a pain in the heiny and wallet.
