If you though HD was all about video then you were oh so wrong. To watch a good movie, you need great sound effects besides a high res video. So while being able to watch Blu-Ray disks on the Playstation 3 was wonderful, it did not allow consumers to listen to DTS-HD Master Audio.

Teen pregnancy flick Juno, which is released on Blu-ray in the US on 15 April, will support DTS-HD Master Audio with up to 5.1-channel surround sound. However, the audio format can support 7.1-channel sound.
