DD+ is a better codec and gives better quality sound. It is what Netflix use for 5.1 audio.

Some older AV amps can only decode regular DD 5.1 and and feeding them DD+ 5.1 will result in stereo output.

Apple TV outputs regular DD 5.1 I'm guessing it re encode the DD+ to output regular DD. Another possibility is that Netflix feeds the Apple TV with regular DD 5.1, given that Netflix produces around 90 different encodes of any one title for various devices and streaming quality options. I'm not sure which one it is.


The WDTV Live, which I use, sends DD+ via HDMI and regular DD via optical. This is useful to me as the lounge AV amp can decode DD+ but my older bedroom one can only decode regular DD. The WDTV must reprocess the DD+ to produce regular DD via the optical output.
