Before I start transcoding most of our blu ray collection from MKV to M4V for viewing with an ATV3, I thought I'd check and make sure I'm doing things correctly audio-wise. Here are the steps I've been following so far: 1.) Make MKV-- select DTS-HD or TrueHD for audio 2.) HandBrake-- use high profile setting which provides two audio tracks. For example: DTS HD MA --> AAC (Core Audio), Pro Logic 2, Auto, 160 DTS HD MA --> AC3 (ffmpeg), 6-channel discrete, Auto, 640 Is this correct? ATVs can't handle pass thru, right? When would you select pass thru? Lastly, I selected DD 3/2+1 instead of the HD audio option within MakeMKV for my first few tries. I later learned that it's best to select the HD option instead. Is it worth it to go back and do these again? Any help/advice would be greatly appreciated!
