Mark thanks for your advise. So far I just removed the optical cable from my Arris, and went from the Tv to my Denon, everything works so far, but I didn't try my dvd as of yet. I almost went out and purchased a new amp, so you saved me some bucks....lol...I am still fooling around with it. I have two Denon's and the other one is 100 watt/channel while the one I am using now is 75, but sometimes when I crank it, it blows the breaker on the Denon, ( have to be careful with the volume I guess). I thank you for your help, and will let you know what's going on when I do set up the other one. Will have to use rca jacks with the older Denon, but it will be the same as using the optical cable, but I suppose the sound signal won't be the same.??
