Thats the idea of a remote control. ***WIRELESSSSSS!***
The PowerMids and other extenders discussed here are IR Blasters. The unit that sits in front of your equipment blasts an IR signal to the equipment. For simple set-ups this works fine. For more advanced systems it does not so IR emitters are used which are small bulbs with thin wires that are placed over each individual component.
You would want to use IR emitters in the following circunstances:
1. You have multiple units with the same or conflicting IR controls. Two of the same cable boxes, a Sony DVD player and a Sony VCR that may share like codes, etc.
2. Your equipment is tucked away snugly in a cabinet where a blaster signal cannot be placed to easily reach all units. Again... not a problem when you have a cable box, dvd player in tv. But, in my home my equipment rack houses a cable box, direct tv receiver, av receiver, dvd player with hd upconversion, dvd/vcr, dvd player with Divx playback capabilty and more. They stack up pretty quickly.
Remember the nice thing about the radio shack pieces is that if they don't work for you you can easily return them
