Can anyone get FMV in games to run in NT???

I have a Athlon K7M 650mhz with 128MB of RAM, SB Live! & Voodoo 5500 AGP

I am running under the latest BIOS with the latest driver updates. All my games run 100% solid in Windows 2000 but the cutscenes are quite jittery. It's almost as if the video and sound are interfering with each other (?) Has any1 found a fix? I observed many people are having similar problems with Monkey Island 4 and no solution was posted. I tried turning my hardware acceleration down but it did not work.
