Hi, not sure exactly where to post this, I have connected my t.v to the bluray surround system via an optical cable, I have connected both the Sky HD box and the Bluray Surround system to the T.V via HDMI cables. I went into Sky sound options and changed the HDMI sound to dolby digital, this worked fine with all channels except for Sky movies, where I have no sound, I have to change the HDMI sound setting to the default to get sound on Sky movies. Is there any way round this, as I really want to be able to have my hdmi sound left on dolby digital without connecting the optical directly to the sky box.
