There is a problem with TV Output where you will get some feedback noise (a wavy line running across the screen
sometimes with some audio noise). This is sometimes associated with the TV Input cable from your Aerial connection
or possibly Cable connection (any cable that hooks into the TV's tuner connection). A quick solve is to disconnect
this cable when using the computer's TV Output. A more time consuming fix is to try finding which cable is causing
this and replace it.
