Ok I took a look into where the issues are occurring; the DVD window seems to be creating a window larger that your screen (probably bordered) and it's doing that as a child window.
But the latest version uses a borderless window if you select windowed mode. So until I have a proper fix you can try thing; go into OGLSetup.exe, set the resolution to match your monitors current resolution, and then tick "windowed".
It's not ideal but you can play the game full screen with movies. Having tracked down the cause it shouldn't be too hard to come up with a workaround with a borderless fullscreen mode.
Hi Pedro, thank you I think it will be a good compromise. I have tried to download the "Model Upgrade Pack" but the link seem dead.
I hope to found someone that can upload it again.
