Hi forum folk, I started ripping my DVDs via MakeMKV and then converting to M4V with Handbrake. Takes a little while to do the conversion but that's okay. My only issue is getting 5.1 sound. I have a surround sound system and I'd like to be able to utilize that with the digital copies I'm making. Otherwise I may as well fish out the disc and use that if I want to watch one of my older movies. From what I've read, I understand I need to make sure the file is AC3(ffmpeg) under Codec. What I'm not sure of is the Mixdown tab. A little guidance is appreciated.
