I'm using multiple monitors and I'm also experiencing this problem with some video sites. However, it works on some other sites, so I'm not quite sure what they are doing what the others aren't. I don't have this problem with any video players on Windows, so it can't only be the video players' fault.
The problem: I play a Flash video on one of my four monitors, press the Fullscreen button and it fullscreens on the most left montior, regardless of where the browser window is. (I also had this problem when I was only using two monitors.) What should happen (which happens with some players): The fullscreen view of the video should open on the same monitor as the browser window is on.
