Does anyone know if the PSP can be connected to an external hard drive via the usb port. The only reason that I ask is that I think it would be awsome if I could put some movies on my iPod and play them through the PSP.
I've seen nothing (and heard no rumours) about anything like this, but I wouldn't be suprised to see a 3rd party vendor make something like this. The places you would probably see this 1st would be http://lik-sang.com/ and http://play-asia.com/ so keep an eye out.
As for using an iPod to do this I couldn't ever see this happening unless it was formated for Windows use, not Mac.
