I have tried moving the file from my pc to my 2TB hard drive but it keeps saying the file is too big. How can this be when the file is only approx. 8gb? How do I get it to play on my ps3??? :(

Some filesystems (i.e. FAT, used frequently for external media for compatibility purposes), have a maximum filesize they can accept. Try reformatting the drive to anything other than FAT.

EDIT: yes, but that would probably break compatibility with the PS3. Just burn it to DVD and be done with it.
