i know its possible to play high def on a monitor but i have only heard of it being possible using x2vga, is this the only vga box that can do it? also i have a uk/pal box can it even show high def? it is chipped and i heard there was some workarround setting it to nstc output or something? can it vbe done and is it worth it? also if i do connect it up i would love to be able to connect it to the surround speakers i have on my pc, does the xbox support 5.1? and if it does how do i get it to do that?
