Surely if you just remove the video the game will look for it, not find it, and crash. On the PC the classic method has always been to replace the video with an empty file, that way the game still finds the right file but there's nothing there.
So in Windows you could just make a new plain text file, rename it to the same name as your video, and replace the video. It might work, you never know.
EDIT: looks like I misunderstood the query: I thought you'd already remade the ISO after removing the video and it got stuck. I think mz's suggestion is better then.
