Hello everyone, at the risk of bringing the roof down can I ask a very simple question. Can some kind person state precisely which, if any, off-air TV sources carry Dolby 5.1. I understand that the Sky HDTV box will have a digital audio output carrying 5.1, what is likely to happen if I connect this to a stereo audio DAC? What is the situation with Freeview, I have a Humax box with optical digital output. Thanks in advance. Martin
