My question is, what are my options? I've heard of home networking setups that use the (in my case fairly modern) house wiring itself for the LAN--do those work well (or do they even exist)? Another possibility is to get a wireless DSL router/hub, but then I'd have to get some doohicky for the XBox, and I'm afraid of interference from cordless phones and such.
Finally, there's the "Mohammed coming to the mountain" solution-- bringing the XBox upstairs and getting a VGA adapter for the XBox to feed into my flatscreen CRT. It's pretty crowded up here already though, and I want to avoid that if possible.
I would avoid the "home networking setups" - they suck. I have a fairly new home, and it was very unreliable. You could do the wireless setup and that is good....but your "Mohammed coming to the mountain" has A LOT of appeal. Why? Because of the vga adapter. If you are going for either the x2vga or the vd-z3 you are going the high def route!!! I would do that, imagine playing a game in 1080 rez :twisted:
