I think if Microsoft had made a silent low power box with MCE on it and marketed it as a DVR they could have had this whole market. I still don't understand why I can't walk into retailers and see such things on the shelf. I don't understand why it isn't built into the standard xbox. They have a device - it's in the living room already and it's even already connected to the TV. But it doesn't run their DVR software. There's something very inexplicable about it all.
