I have an Apple TV that is having some trouble with random stutters. I'd like to see if I can correct this by adjusting my MKV files (h.264 + DTS) to h.264 + AC3 5.1 in an mp4 container (or m4v).
My problem is when I use the optimize feature on plex, it will convert the container to an mp4 with aac 5.1. My receiver (and as far as I know the AT4) does not support AAC 5.1. Is there a setting I can change to make an optimize profile that utilizes AC3 5.1 instead of AAC 5.1 so that I can direct play?
