The official PSP (PlayStation Portable) Website

Here it is. This site says if you sign up you get the Spider-Man 2 film for free. At least, I'm supposing its the film you get and not the game. I like the idea of watching movies on a portable device - say when on a train for example, problem is of course that UMD is just another format and hence another way for manufacturers and distributors to make more money by reselling the same content several times. In this day and age, we download licensed music in the form of Windows Media Player WMA files - why can't they work out how to encrypt movies so that they can be distributed in licensed form too?
