I checked the back of the TV and the back of the Satellite box.
The Satellite box only has two USB ports and 1 optical out. The HDMI and 2 Satellite ins are being used.
The TV has 2 USB ports, 4 HDMI ports, 1 Satellite in, 1 optical digital audio out, and 2 ports which I’m not sure what they are - 1 says audio out/ H/P and the other says RS-232C (SVC only).
The Lifatec Toslink is an optical digital cable? It seems like this is the cable I will have to buy right? And I think it would be better to plug it into the TV as the TV is also used for Netflix not just the Satellite.
