Tip - How can I copy DVD movies to my Sony PSP? - Ask Dave Taylor

I really love my new Sony Playstation Portable (PSP) and while most of the games are kinda lame, there are enough good ones that it's a great companion on my daily commute. I bought a few UMD format movies, but I have a HUGE library of DVDs that I got for my home and I'd love to be able to copy some of them onto the PSP rather than have to buy UMDs. Is that even possible, and if so, how the heck do I do it, Dave? Help me, please!
