I don't think I'm allowed to post links to this so I'll just describe it. There is blackberry site that I have used for the past year to download movies to put on phones. They are mp4 files. They play flawlessly on my droid X, but on the xoom, the movies aren't very smooth at all. File sizes are about 700 mebabytes each. The next question is what format will play nice with the xoom. I would like to start ripping my own DVD's to take with me, but I would like to know which ones are going to look good before I do it.
