I am new to HDTV and AUDIO systems so please be patient. I have a 55" Sony LCD projection TV and recently purchased an LG "Home Theater in a Box" 5.1 surround system. I have the surround system connected through the Audio Out port on the back of the tv through a Fibre optic digital cable.When i play my PS3 or watch a DVD everything runs great. When i attempt to watch TV through my standard def. satellite reciever there is a lag in the sound of about 1/2 second between the TV and the Surround speakers. Any idea as to what the problem is ??
