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?
