Lets start with video part. Assuming your TV has at least one component input, you can buy a Component A/V switch, with at leat 4 inputs to connect DVD, xbox360, apple TV, and Ps3 (the wii is SD)
Assuming your DVD player (or Hometheater in a box) has an AUX input, you can also buy a digital audio input switch (probably optical). If not, there is nothing you can do without an AV receiver.
Look at Gefen, but there are cheaper options as well.
