its 1080p through component (which very few tv's support) or vga. it is still fairly new so it plays hd dvd's...but doesnt upconvert regular dvd movies. it IS possible to hook it up to your computer though...but in order for it to work with your comp, all your stuff has to support hdcp encryption.
there is a huge rumor going around about a black xbox360 with stuff like HDMI and other things. i would wait. microsoft is bound to update to compete with sony on the hardware side of things very soon.
I havn't seen any post here , so I will ask. Has anyone had any exp. with the 360 HD player.
