This is one interesting product, at first I thought it looked like a mac-mini, but I was wrong. It so much better then that, it upconverts any input/DVD to 1080p or whatever the highest resolution of the screen. It also acts as a switcher for all the inputs it has. Its priced at $400, but if it works as advertised its a great piece of electronics.
Inputs:

• Two Components Input
• Two HDMI Input

This product is filled with features for the quality to be high, and making sure the upconverting is done right.
