Problem converting FF9

[Momonari2003]

Hi! First of all, I sorry if this is the wrong place to post my question.

I converting all FMV's of Final Fantasy IX using the PSXMC, I sucefully convert all, but the ENDING fmv I have no luck, when I see the preview on the program, is go all right, but after converting to .avi (using the codec MICROSOFT MPEG-4 VIDEO CODEC V3) the audio go a little faster and the video play all right, this problem is only on this FMV.
I using the original copy of FF9, nothing of backup...I confused

HELP !!

Thank's..

You will find that Square protected their final movie by changing bitrates of the video and audio, they dont match when converted but will play ok not converted.
