Has it actually been confirmed, or people think it "should" work, technically.
The author of BD Rebuilder is not interested in Atmos itself and most people ripping discs with Atmos are only interested in getting the TrueHD track working (which mainly involves ignoring the Atmos metadata).
Eac3to does not yet handle Atmos demuxing/remuxing and there were a lot of issues getting DTS-HD to work because the extensions were not understood, so I can see there might be lots of issues with Atmos. With TrueHD and DTS-HD MA I understand there are often duplications of audio data at the beginning or end of seamless branched files: eac3to takes care of this, but if the same is true of Atmos metadata, which is not yet understood, there could be glitches.
Of course I could be completely wrong and it's simplicity itself to demux the entire Atmos audio track and remux it back together as one intact file and BD Rebuilder will handle it just fine.
I think Atmos is just another opportunity for the studios to inhibit manipulation of copyrighted files to force migration to new hardware, however temporary.
