I checked the space on my laptop and I have 127 gb of free space so I'm just going to download to my hard drive. I think I will make a backup on a couple memory sticks.
My husband put my other downloads on our PS3 so that I can just play them from there. I'm not sure if he had to do anything to convert the format first or if he just copied them over from a memory stick. Sorry, I know that isn't a lot of help!
