Audio out of sync on some games

[CroniX]

Hello all, I've had this problem for a while now and am at my wits end trying to find a solution. When I try and play either Odin Sphere or Wild Arms 5 on my ps2, the game runs fine, but in cutscenes the audio is about 10 seconds out of sync with the video & its driving me crazy. I am using latest swap magic on a PAL ps2, and have tried burning both the games on slowest speed using Nero, Alcohol 120% and DVD Decrypter on TDK DVD + & - R's and Sony + & - R's, but they still keep having the problem. Any help would be greatly appreciated, thank you.
