It's the opposite. For the compatibility with the 2D-only players, it is necessary to put the main movie in 2D in standard M2TS files. The second view is therefore in another M2TS, not readable directly with a 2D player, because it is encoded in MVC and is therefore dependent of the main 2D M2TS. The two M2TS files are interleaved at the file system level, and the SSIF file is a file level trick that references both streams at the same time, exactly as if it is a single file. It's why you copy two times exactly the same data if you copy the M2TS and the SSIF files to your hard disc. Normally, the SSIF is never created directly by the authoring program. It is created when the image of the BD is built. (BTW, I don't know if the 3D players prefer to read the two M2TS or the SSIF, but in any case a file is not necessary. The MVC M2TS is useless if the player reads the SSIF, and the SSIF is useless if it reads the two M2TS. The main M2TS is necessary to play the movie in 2D anyway.)

I have already used MkvMerge without problem to do just that (with The Hobbit). It works perfectly and it keeps the audio, subtitles and chapters correctly synchronised in the second part. IMO, MkvMerge in "append mode" is the best solution.
