According to its spefication, this player only supports Dolby True HD decoding (5.1Ch). So it doesn't decode blueray movies with True HD 7.1Ch?
From the product info: Sound you can feel Experience the highest sound quality with Dolby TrueHD and dts-HD codecs which reproduce high-definition sound with 7.1 channels of discrete audio for uncompromised quality.
You should stop answering as you have no clue. Dolby TrueHD and DTS HD 7.1 are both reproduced on this player. In fact there are very few Blu ray players that do not. There are hundreds of 7.1 channel titles and as I own this player each one of the 8 (7.1) channels are reproduced.
