Getting going ripping my Blu Ray media and I've read a ton about it. My goal is to have a 1080p video with 3 audio tracks: stereo (for iDevices), 5.1 surround (for my ATV playing through my surround receiver), and lossless (futureproofing). Thought I was doing everything perfectly but I've got a devil of a time getting audio out of my ATV2. My work flow as follows: 1. Rip Blu Ray using MakeMKV: selected the DTS-HD MA audio track 2. Transcode with Handbrake: Track 1 - 0: English (DTS-HD MA) (5.1 ch) Codec - AAC (CoreAudio) Mixdown - Dolby PL II Track 2 - 0: English (DTS-HD MA) (5.1 ch) Codec - Auto Passthru (for some reason AC3 Passthru was not on the pulldown list, but under advanced options I disabled all but AC3 with a passthru fallback of AC3 (ffmpeg) Mixdown: n/a Track 3 - 0: English (DTS-HD MA) (5.1 ch) Codec: - DTS-HD Passthru Mixdown - n/a The result is a clip which plays audio on the Mac (either it's doing Track 1 Dolby PL II or it's properly decoding Track 2) and on my iPhone (properly decoding Dolby PLII) but not my ATV. Things I've tried (based on suggestions in these forums): - Setting the ATV audio to Dolby Digital ON - Setting the ATV audio to 16 bit - Saving in Subler with only Track 1 checked - Saving in Subler with only Track 2 checked - Saving in subler with both Track 1 and Track 2 checked (desperation) The only odd thing about the process is that AC3 Passthru doesn't appear as an available codec, but I believe what I did with Auto Passthru forced the same thing. In fact I'm sure of it, because Subler reports Track 2 is AC-3, 6 ch. I am offered "AC3 (ffmpeg) as a codec, but only with the following mixdown options: Mono, Stereo, Dolby Surroud, Dolby PL II, and 6-channel discrete, none of which will give me 5.1 surround out of an ATV. Odd that Dolby Digital (what I'd want) isn't on the list. Any heroic Handbrake experts out there? Thanks a bunch.
