It's possible, but the quality would suck. As S-Video is (I think) limited to NTSC 525i video quality. Do you have the component video out on your X-Box? This should be available through the media expansion or whatever M$ calls it. I'd go to your local Radioshack or whatever and check if they have a component to VGA converter (so you can connect it directly to your monitor). Then you can enjoy some high resolution gaming on your nice monitor.
