I am assuming you are using Save states, and not the actual in game save when this happens. What you need to do is load the game through the in game load screen (select your most recent in game save, though it doesn't really matter how old it is). Once that is loaded, simply load your save state and the FMVs should return. This worked for me for FF7
also, try using the search feature a bit longer next time. I have answered this same question multiple times on these boards.
