How can I connect my Wii to a comcast HD dvr cable box?
Unlike the poster above me, my comcast HD DVR indeed does have both video inputs and a power supply input; the brand is a motorola dual tuner dvr (comcast). If yours are different, and I have noticed in different parts of the country they do indeed use different boxes, you may want to invest in a switcher. With a switch you can hook up all of your electronics and it will automatically switch the feed between then , I have found for the $100-$300 they cost, it is the most practical solution if you have a bunch of electronics.
