You put a disc game in the hard drive folder. Don't do this as it conflicts with game installation. Put the game anywhere else (your desktop, C:\games, whatever) and use the boot --> boot game menu to select the folder.
Furthermore make sure that the structure is such that the folder USRDIR and several other files and folders are inside the folder PS3_GAME and that the file PS3_DISC.SFB is next to the folder PS3_DISC, not inside it or anywhere else. Move it if need be.
Also set frame rate limit to auto in settings, not off.
