Avoid Changing Discs
It can get very tiring to load your game of the 1st disc, then switch to the 2nd, etc. but there is a way to avoid this. When the screen pops up that says "Please Insert Disc 2" simply press the Triangle button and you'll proceed without having to change discs. NOTE: You won't see any FMV by playing off of the 1st disc, but you'll still get mission briefings, voices, and everything else.
