So I'm just wondering about video/ audio synching issues. If I just drop the MKV and audio into visualhub and tell it to do Apple TV setting (5.1) and "go nuts" it should come out ok right? Should I manually set the frame rate to ensure the audio and video are in synch? I'm not really worried about the 5.1 audio. I don't mind if it's just 2.1 aac, I care more about the audio being in synch.
