Installed DLC for games don't show

I'm trying to get my DLC maps for my COD games to work. I've got all the maps installed, but none of them show available.
I've tried searching, but everything leads me back to the how to install updates. I got that, but can't figure out how to get my DLC to work.
Are there files I need to copy from my PS3, other than the game directories, to allow me to access my DLC?

... unfortunately i can't help you with your issue but i am curious - why do you want to play the PS3 - COD instead of the PC - version, which is technically better and not bottlenecked through emulation?

Because I like emulation and I thought my DLC could be installed on the emulator..
I own most all COD on PC, PS3,X360,XB1
I only play the multiplayer aspect of COD. Since the multiplayer aspect is working great, I'm trying to add my DLC to it.

I spend most my time on PC playing Break Point. I get lost for hours, just hunting. I don't do objectives. haha
