Here in Minneapolis I have Comcast HD.The digital out's on the STB all put out Dolby 5.1 regardless of analog-digital-or hd.However the analog outs will vary And put out the broadcast signal whether Dolby-mono-stereo.It also will vary depending on if I am watching digital or analog channels with the digital being better.My Hitachi has digital outs but if I run the analog signal in it only passes through what it gets coming in.Basicly if you have a stb with digital outs your odds are better using them.
