What Version of HDCP Does the Xbox 360 Require? Other HD Questions...NERD ALERT!

I might get an Xbox 360 some day (say I win the lottery). My HD TV has support for version one of HDCP (High Definition Content Protection, supposed to protect against copying, yeah right). Is version one sufficient to use an Xbox 360 with my TV? Also I only have one DVI port on my TV, no HDMI (it's two years old, my dad kinda jumped into it). We have our HDTV Star Choice satellite receiver hooked up to that, so I don't wanna have to swap out the satellite for the 360 everytime I wanna play in HD (I have a CRT TV in my room which I usually play games on). Can I get a Y shaped switcher thingy for my TV? I know DVI, unlike HDMI, doesn't support all in one audio and video in one tiny HDMI cable. Does the 360 have a seperate output for audio, too?
