can it be downloaded to PC?
There is a way to do it, and then transfer to PS3 using a proxy program
You need a router in which the PC and PS3 are both connected to.
My PC is hard wired, and the PS3 wireless from the same router
Basicly you start the proxy program on the PC, get the PS3 to start downloading. The URL will show in the Proxy program
Copy this url and download it on the PC.
Once finished, you set the PS3 to use a proxy in the network settings --> using the proxy program's address.
Set the proxy program to intercept the previous url and point it to the downloaded file.
PS3 will think it's downloading the actual file and it will install it etc from your PC
This is one way to grab large files away from the PS3 etc. It's handy as download accelerators work, and the speed tends to be faster on the PC
