djtOtago: You said laptop, So why not just connect your laptop directly to the TV. Most TVs have a VGA connection to support older laptops. Most newer laptops would have a HDMI out connection.
computernutter: thanks for the reply. What I want is to have my computer screen transmitted wireless to the raspberry pi, so I can watch videos that are running on the computer (lets say a youtube video) on the tv screen that is hooked up to the raspberry pi.
