New HWS installed a few weeks ago. Have one TV hooked up with HDMI thru an older Harman Kardon receiver, which is working great. Wanted to mirror to a second TV using the component video and optical audio, but there is no audio output over the optical. Is this normal, maybe only allowed to have one digital audio output at a time? Or is my Hopper broken? Got around the problem by plugging the optical cable into the optical out on the HK receiver, but I'd like to be able to use the second TV independently without turning on the receiver.
