My Premiere and AME are both updated to 4.0.1. I'm trying to encode with multi-channel to an Apple TV compliant h.264 (non-bluray) file. The audio encoding allows multi-channel AAC (which I believe may be unrecognizable by my receiver), but not an option for the Surcode AC3 codec. Surcode is available under h.264 blu-ray and MPEG-2 DVD, but is not an option under the normal h.264. How can I encode a multi-channel audio track for an Apple TV? (The blu-ray option does not allow me to pick my required resolution of 960x540 29.97 fps). And is this $300 plug-in my only multi-channel option?
