Hi, I'm new to cTivo and I am having a hard time creating a custom encode format and wondering if anybody can help me. I want to use HandbrakeCLI with dual audio streams to watch on an AppleTV3. 1. I get audio sync issues when using mencoder, so instead I have been using the Handbrake AppleTV preset 2. I started by duplicating the existing "Handbrake AppleTV" preset and simply copy/pasting the code that tannebil provided above to get dual audio streams. I cannot get it to work. My encode works fine, but I only have one audio track (when viewing the audio tab right on the appleTV, it says "Unknown Audio" but there's only one track). Note: The source program is movie that I recorded a portion of from TBS, and it's in HD w/ 5.1 dolby digital audio. So my question is, what am I doing wrong? I attempted to copy the code above directly into the "Video Options for Encoder" field (over-writing the -z"AppleTV 2" that was pre-filled). When that didn't work, I left the -z"AppleTV 2" in the video options field and tried pasting the code into the "Audio Options for Encoder" field. Lastly I tried pasting only the portion of code related specifically to audio (-a ... ) into the audio options and neither of my attempts gave me what I wanted. I would be grateful if anybody can provide a step-by-step on how to get dual audio streams (I want AC3 pass thru as well as an AAC version that will work on an iPhone). Thanks- apologies if this is supposed to be obvious but I'm just not sure how to supply all the extra coding required even after reading through every post in this thread and visiting the Handbrake Configuration page (I am a handbrake user and have had success within Handbrake itself getting any number of audio streams to select on my ATV3).
