I have used VNC to peek on someone playing an FPS shooter, like Unreal Tournament or Elite Force, and other graphic-intense games. The result is usually the same with most DirectX-related software -- the image is wrapped and overlaid in a weird fashion in that you really can't make out too many details, but enough that you can recognize what game they are playing. Even if there wasn't an issue with resolution and the like, VNC can't really keep up with the game's framerate.

Think in terms of where the image is produced. Your TV card adds the TV image to the video stream after it has left the CPU and before it gets to the monitor. It's a hardware video player. If you play DVDs on your computer, you have the same problem. If the card adds the DVD image, you won't see it on VNC, but if the DVD stream is created by *software*, then you will see it. I don't know what an FPS shooter is, but the same logic applies -- where does the video for the shooter get added to the video output stream? If it is added after the CPU, then it won't be in vnc.
