A:AnswerHi, hfd79!
To ensure that you get sound when you select DTS-HD Master Audio 7.1, please check that your Audio System/AV Receiver supports that format. And the narrative that you hear when you're playing a disc is most likely a feature on the disc that you're playing. Please check the Audio language settings of the disc to disable the feature. -Sam
A:AnswerThere are wall mounted shelves that can handle this player, with a very small footprint. If you are thinking about placing the bottom on the wall with the face facing the ceiling, No! That's not how it's designed and you may get the disk lodged inside the player causing damage! The remote signal will not reach the receptor effectively either!
A:AnswerHi, Hedo! The HDMI OUT 1 jack is for both video and audio content, while the HDMI OUT 2 jack is for audio only. Use the appropriate HDMI jack depending on the intended use. ~Ralph
A:AnswerHi, Patricio! Unfortunately, the unit only supports Region 1 (DVD) and Region A (Blu-ray). Sony doesn't make or sell region free or multi-region players. ~Ralph
