I've started encoding MKV files made from Blu rays for the first time using the Apple TV 3 preset in Handbrake. Is everybody use the settings as is for that preset or has anyone tried tweaking the settings some? I've tried the ATV 3 preset with the settings it's set at and gotten one movie file around 8.5 GB but other 2 movies I've encoded have been around 3.5 GB which surprised me. Also are the audio settings correct in that preset or has anyone tweaked those settings as well. I mainly view my movies on ATV 3 on a Samsung 46" LED no surround speakers but may at some point get a 5.1 surround system.
