NTSC PSX games on PAL PS2

[Dragonz]

Hi I have aproblem playing final fantasy IX(NTSC format) on my messiah modded PAL PS2.WHen I use ImportPlayer Light the game works fine and without frequency(flickering picture) or coulour problem but the sound in in-game movies skips.Do I have to use NTSC-2-PAL patcher to remove this problem or is there any better ImportPlayer out there, that doesn't has this problem.

Thanx!
