I'm using Handbrake to encode videos into the Apple TV3 Preset (well a slight variation mentioned here).

The only audio tracks I put in with Handbrake are the 5.0/5.1 ones.


When I look at the resulting file in Subler, however, it shows the Surround 5.1 track as not enabled and a 2.0 Stereo track enabled.


(My iMac has only stereo audio, but the AppleTV is hooked up to a Sony Reciever with surround etc).

I think my AppleTV is sending surround to the receiver and that's what's playing. It sounds like it and the receiver has the right lights on....

Is this just a Subler thing or is there something I'm doing wrong?

What's the question?
It's all by the book on your pic!
AppleTV spec movie has to contain an AAC stereo track and may contain AC3 surround track.
If present, the surround track must not be enabled.
AC3 playback on Mac - OS X doesn't have AC3 decoder. It used to be Perian, which is now defunct in 10.9 (unless you have QT 7 installed).

Track attributes are set appropriately. As long as your connections, appletv, receiver are set correctly you'll get DD. Your receiver will indicate if it's playing DD or not.

On AppleTV you can select which audio track to play, along with subtitle and chapter selections.
If enabled in settings, the DD track in your preferred language is selected by default on playback. But you can always change and hear-see the difference.

Wow! So the ATV cannot downmix to Dolby Prologic itself and you include a second stereo track? How lame!

What's lame? The movie standard is meant for all iOS devices. So basically the same movie plays back on an iPad or iPhone.
You can have a movie with AC3 track only, but these will play mute on iPads and iPhones.
Also, as such, having the device to do as little CPU intensive tasks during playback as possible, is the best way to go. Esp on a portable.
And last but not least - they are all optimized to iTunes ecosystem, so the average user doesn't even need to know or care. All media downloaded from iTunes plays as intended, with more effort made on production side and leaving the playback side as lean as possible.
