I don't know what these ds_store files you have in there are, I've never seen them in a resource pack.
The only textures you have are the cooked pork chop and the title stuff, so that is all that will show up.
If you are simply putting this whole thing in your resource pack folder, then it will not work. You have to take the first folder called Minecraft out and put that in with the resource packs. I do not believe the _MACOSX will work due to the items having ._ in front of them, but I am not familiar with Macs.
The title folder should be inside assets/minecraft/textures/gui and the folder called bg should be called background. The credits, splashes, and win should be in assets/minecraft/text.
There might be other problems, I am also at the level of fully understanding it yet. Try moving these things and see how it works. I do not have the time to test it myself, sorry.

Willy Wonka didn't send aliens to blow up the Sparta, while teaming up with JOHN CENA, Nyan Cat, and Good Guy Greg, did he?
And where's Bill?
