I bought a used copy of Quake 4 for the Xbox 360... it works fine and all... but I noticed on the back of the box it says "Also Includes: - Quake 4: The making of
- Quake 2"

Now... i tried putting the game into my DVD player... which i thought would let me watch the making of Quake 4... since that didnt work, i dont think im supposed to put the game into my computer for Quake 2... can anyone please tell me how to access these two features? Do i have to beat the game for them to be unlocked or something?

Thanks...

on my copy, it came with a second disc that had that stuff on it, and it was all played on the 360 as well.
