Trying CloneBD v188.8.131.52 64-bit for the very first time, loaded The Great Gatsby 3D for Movie Only backup, and there are Main features #1 and #2 of identical length, though the "Estimated uncompressed size" is close-but-not exact for each. Can someone please tell me that the is normal for a 3D movie? That these two "features" represent the two images that comprise the 3D and should both be selected? It's confusing because CloneBD also wants to make a menu for the two titles, which of course I do not want. It seems also CloneBD will allow me to make a BDMV folder of this, but I thought it only did mkvs of 3D discs? I should note that I want to make a 1:1 copy i.e. no processing anywhere--maybe CloneBD will make a 3D BDMV folder?
