I am now moving into the great new world. I'm installing a Sony STR-DA5300ES receiver, a Samsung 46" LCD (750 class), and a Blu-Ray Player. I have a Tivo box with 1.3 HDMI output.
Two techies from the local cable company tell me that I should just use the HDMI cables for the video and optical for the sound. They claim that the optical will do a better job and, of course, would be free from RF interference.
I have a 5.1 speaker set up, and unless I move, that won't change. The nature of the room would not allow for 7.1 in any rational way.
The receiver certainly has enough optical inputs to allow me to do this, but, is it worth doing?
I have had RF interference in my office which is above the room with the equipment mentioned. It was so severe that I had to get a new wireless phone system and a shielded USB cable for one of my printers.
Based on what I've seen in this thread I'll probably get answers from both sides, but that's OK.
