I've spent months learning and studying the process of converting full DVD rips into m4v's. My intent is to maintain near perfect quality of my DVD's. As such I am using custom settings in Handbrake that the CLI cannot use, negating the batch encode workflow from the provided guide. I am using Handbrake for each DVD rip, the m4v's will be stored on a local drive connected via ethernet to my aTV 2 and played through XBMC (tested and works perfectly). 1. Tagging info: Need to tag my converted m4v's w/ actor(s), plot, movie poster, and most importantly chapter titles. I am using Handbrake nightly builds for each DVD rip (DVD rips on one SATA drive are encoded to another SATA drive in my Mac Pro). After Handbrake encodes the m4v, I can tag everything except for chapter titles as I cannot locate them online or through importing a .csv. I've searched everywhere, used Subler and MetaX to no avail. What am I doing wrong? 2. Audio Tracks: 1. English (AC3) (5.1), Codec AC3, Mixdown 6-Channel discrete, Samplerate Auto, Bitrate 640 2. English (DTS), Codec AC3, Stereo, Auto, 256 My Pioneer Elite VSX-33 system handles everything thrown at it, 7.1+, THX, DDII, etc. My intention is for the first track to maintain full audio quality for my surround sound system on my Pioneer AVR and Plasma, and a second audio stereo track for iDevices, etc. From my research I assumed AC3 is the best choice with 6-channel discrete to cover all my bases, or is AC3 Passthru the best in terms of keeping the DVD's full audio? Thanks for any help!
