Having different volumes on SD or HD channels I can deal with.
What f***s me off is sitting watching an HD program, getting the volume just right (enough sub action to feel it without waking the family up), then when the commercial break starts the volume takes a step up... it's so f***ing loud pictures start falling off the walls and my girls start crying as they think the house is collapsing.
Mine's ok.. but i got lucky with a Samsung box, apparently they're better!
i got a samsung box and the sound is fine no matter what channel i'm on. Plus it's better with surround sound
