mabrown:You could use the zoom function to fill up the monitor, that's what I do for anything that's still in 4:3.
Yeah, that's what I did for now. I put it on Zoom mode 4, "Intelligent Zoom," and my mom didn't really mind the stretching. However, even though they're running on a 22" widescreen monitor, I'd rather have the Media Center window take up less screen real estate by starting in 4x3 since that's the source of the format that they'll be watching. It's kind of a waste to be forced to stretch it. If Microsoft put the /widescreen command line switch in, I'm surprised they didn't put a switch in for forcing 4x3... even if it was only for testing plugins.
