How do i put sumone elses save data into my game and how do i record my game play footage. to make my own movies

i got it working the problem was the DAF army, not sure why but all the rest are working.

I inserted some of the car mods into vice city but the game crashes, and comes up with a screen saying unexpected faces, now i restored the cars back to normal and only inserted 1 car to see if it worked and it did the game did not crash can i only insert 1 moded car at a time?
