Connect the TV headphone out to the DVD-HTS TV Video audio input.
Adjust the volume of the TV so it doesn't overload the HTS. If it does you will hear distortion at any volume you turn up or down the HTS. If will be best to use the remote of the HTS to adjust volume because the surround sound will work best if the TV volume isn't too low or high.
Try different surround modes to find the one you like best.
