Maybe this has already been posted about, and I know I'm probably being stupid (I blame the flu for fugging my brain!)

But please can someone tell me where I can get the DLC's for New Vegas? Can they only be accessed through PS3 itself or is it possible to download them to my computer and then transfer them to my PS3? I've never downloaded stuff for my ps3 before, except for the usual system updates which I do via my computer.

Thanks!

(I hope this is the right place to put this topic!)
