Damn FMVs. I think we really need to get to the bottom of this, it's getting out of hand!
Okay, "hey" *snicker* here's what i need you to do for me. Play through again, but this time, just before the gongola ride, hold ctrl and hit "tab" to get back into windows. Find your way to your ff7 cd in windows, and go to ff7\movies\ and open "Gold7_2.avi". Let it loop in winamp a few times so that it's in memory. Then try playing through again, see if you get the crash.
if the crash still happens, post again and i or someoen else will get past the part for ya. Though you miss some pretty important stuff between the ride and the next save =/
