FF9 Disc 4 not working!

[Mokujin]

It locks up when when I try to enter the Lifa tree to go the last area. An FMV is supposed to play then, but all I hear is music and a black screen! I have the Paradox release, is there a patch that can sort it? I got the Paradox one from two different sources so its not my laser or a bad burn.
Everything else works fine on Disc 4, I can fly around in the airshp and go to all the other places. But its pretty useless if I can't complete the game.

when i burned mine copy of ff9 with nero it said "error unknown data format" at the end of disk 4 and then i tried it with cdrwin and it didn't say nothing but i think it still got the same problem.
