I happen to have a Blu-Ray with 6.1 audio on it, also known as DTS-ES. This article explains it a bit:

Per that article, there are two types of DTS-ES: A "Matrix" version, and a "Discrete" version. I suspect that my particular blu-ray is the "Matrix" version. Please see the MediaInfo listed below. Notice the "Channel(s)_Original" field, and the "ChannelLayout_Original" field:

MediaInfo is basically saying that there are 7 "original channels", but the audio track is still basically a 6 channel track (a.k.a, 5.1). So I'm thinking that the track basically contains some extra data for a center-rear channel, but ultimately it is still a normal 5.1 track. Am I correct on this?
If so, my question is: How exactly does Handbrake handle this weird audio track? Under the Audio tab, it is still listed as a regular 5.1 track, and as such, I can only do a 5.1 mixdown. There is no "6.1 mixdown" available.
I'm guessing that extra "center-rear" data simply gets dissolved into the left-rear, and right-rear? Is that correct? Or is Handbrake not designed to account for this? Thanks in advance.
