Smackdown vs RAW 2010 PS3 problem?

On create an entrance movie I have a big problem. I can create the whole entrance fine but its when I finialize it there's a problem. When I press finalize it goes onto the loading screen then after a few seconds my PS3 shows a message saying please wait and it stays on there for ages. I have to keep pressing the PS button and quit the game and it wont save what I've created. Anyone else have this problem? Thanks.
