Apart from HDMI output for audio and video , what other outputs are there in ADTV HD STB ? I have a receiver which only pass-thru HDMI audio . So does ADTV HD STB have either optical or co-axial audio output ? even in these does both outputs support 5.1 audio ?I just want to get the respective cable when the STB arrives. thats why. Thanks in advance.
