Seamless branching on DTS-HD MA

Hi there!
First of all, congratulations Rocky! As a long time user and great fan of this incredible program, it's getting better an better!
I know seamless branching is a PIA, and I'm sorry if this has been covered before, but I didn't find anything pertaining a DTS-HD MA audio track. I'm also sorry I'm not knowledgeable on technical aspecs, so please pardon, but I'll try my best to explain.
I've done some testing with Ghost Rider: Spirit of Vengeance USA BD. It's a branched disc that uses DTS-HD MA for the main audio track.
Muxing with the latest Makemkv (1.16.5) and than demuxing with eac3to produced the exact same video stream as direct BD demux with DGdemux, but the DTS-HD MA file of DGDemux was slightly smaller than that resulting of Makemkv mux.
I decoded both files on w64 and compared them on audacity. The conclusion was that the time stamps start out the same, but the end the DGDemux on is -10ms ahead of that from Makemkv.
I know it's a negligible difference, but I just like to understand what's been done differently between the two softwares and which resulting file should be most accurate?
Thanks a lot!
