PSX NTSC game problem on PAL PS2

[Dragonz]

Hi I have a problem playing final fantasy IX(NTSC format) on my messiah modded PAL PS2.WHen I use ImportPlayer Light 2 the game works fine and without frequency(flickering picture) or colour 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.If I don't use anything to boot the games the screen flickers(fequency problem) but the colour is O.K. and the sound in movies doesn't skip but because of the flickering screen I can't play the game.

Thanx!
