I'm using a dual monitor setup with my primary monitor (LCD panel) in one room, and the second monitor (InFocus IN76 projector) in a second room (theater). I want to have MC on the LCD in standard mode and full screen video in the theater at the same time. However, when I click to play a DVD from standard mode, the primary window minimizes and the projector goes black, no image at all, however I can mouse to the edge of the second screen and get the display window chrome to appear. If I click Close Display on the second monitor, Standard View reappears on the primary monitor and the DVD starts playing in the small lower left corner. I can occasionally get full screen video on the second monitor, but it seems to happen at random, and when it does I cannot control anything from the second monitor, no mouse is ever visible.
I'm guessing this some kind of setup problem between MC12 and the nVidia control panel, but I can't figure out what. This doesn't happen in TheaterTek--I just tell it to use monitor 2 and it plays no problem.
