Around the Christmas season, I decided to purchase a surround system.(LG) and I hooked it up and it sounds great. The 'HUB' is also a blu-ray player and I have my 360 running through the component part(so it works through SS). For me to switch it over and for it to work, my blu-ray player must be on and I have to switch to AUX, etc. naturally. The problem im running into is this. The Blu-ray player is running off HDMI and so is my PS3(I have 2 HDMI ports on my TV). I have been suggested to buy an optical cable and run it from the PS3 to the Blu-ray and switch it that way. Would that conflict with the HDMI?
