Tales of symphonia jpn opening slowdown

[Shaoran_Rendan]

Hello everybody!
I was trying to play the japanese version of tales of symphonia for GC with the emulator and I noticed that there are some slowdowns in the opening movie.
I tried the US version and it has no slowdown, is there any way to play the opening without the slowdown?
My specs
Core 2 Duo E4500 2.20 ghz
2 GB Ram
Radeon HD4670
Vista x86/also tried with 7 x64 with the same slowdowns in the same part

I tried with both opengl and d3d plugin with no difference and with a lot of revision from 4331 to the actual one

Your pc is slightly on the week end but if you can play the us version fine then i don' no what to tell you

It's weird because the us version has the same video with different audio. Besides, the fps counter doesn't goes down in those parts

I'm getting the same type of issue on the US version as well. I find it slightly odd, because my cpu is only at about 75%, and my gpu is barely being touched at all. This is on build 4525 x64 with the opengl plugin.

Specs:
Phenom II 955 @ 3.2ghz
6GB RAM
Radeon HD 4870
Windows 7 64bit build 7100 (yes I know...)
