Anyone Know Much About UMD (PSP) Movies?

[Seil]

Not quite sure if this should go into "Playing Games" or "Movies..." but whatever.

So I recently added to my pile of video game boxes some PSP movies - I have some Family Guy bits, I've got Final Fantasy: The Spirits Within, Starship Troopers, Ghostbusters, The Texas Chainsaw Massacre remake and Dodgeball. I also have Spiderman 2, as it came with the PSP, so there's also that.

I was wondering if anyone had a list of UMD movies available (that's not an eBay link) and some info on why they were discontinued. I had heard that it's more expensive to manufacture UMD movies than DVDs, and since it's a smaller market, companies aren't getting the return they want, so production shut down.
