hey /games/ I have a PS3 problem

I want to play some .mov files via USB on my ps3, but when I plug it in it says it's empty. I've tried this with 3 usb's and it's all the same problem. Yes I clicked on "display all" and yes they are in FAT34.

Anyone with a kind heart care to help me?

Thanks

it's fat32 you fucking moron!
