Installed a Westinghouse 42" LCD w/1080p on the wall. This was quite the task seeing i have plaster walls and the wires needed to be run in the wall that had the air return vents in it.

I had to use "plenum" rated tubing to ensure if there was a fire that the housing itself would not start on fire, then dispurse the smoke throught the house via the air return.

With this adding to the confusion, I planned to run all of the A/V wires (A/V on one side of a stud and power on another) to one corner of the room. Luckily, i was able to use the unfinished basement to my advantage to run the wires to that corner.
