I have a kenwood surround/amp with DTS and Dolby Digital. When using a digital connection from DVD player, the appropriate (DTS/Dolby) light will come one to let me know it is receiving the signal. I have an HD receiver from Dish Network and have it hooked to my HD projection TV via HDMI. I have an optical cable out of the TV to the surround amp but the Dolby light does not light even when programming says it is Dolby. The fucntionality is turned on in my reciever. Any ideas? Thanks!
