This preservation requires that you have the original, store-bought Blu-ray. It also requires that you rip the movie to your hard disk via your preferred method of ripping. You'll only need the movie, not anything else. My vote goes to MakeMKV since it'll work on Linux, Windows, or Mac OS X. Many people fancy AnyDVD HD (which came in very handy when I was frightened that my HD-DVD player would stop working one day and I can confirm that it is a solid piece of ripping software). Once ripped, you'll have a large 20GB+ M2TS video file. Keep it in a memorable place.

Since I love cross-platform tools, the next tool you'll need is tsMuxer. tsMuxer is the tool you'll use to multiplex (mux) your DTSMA file with your M2TS file. If you're using the GUI, simply drag your M2TS and DTSMA files to the "Tracks:" section of tsMuxer's GUI. From here, you'll be able to select your destination type. The choice is ultimately yours, however I chose M2TS because I will not be exporting to physical media. You can choose to output in a Blu-ray or AVCHD compliant file structure for exporting to physical media if you so desire.

OK finally managed to grab this! Thanks to ElDonante and borisanddoris.

Trying to mux in the track using tsMuxer however it keep getting "reading buffer overflow. possible container streams are not synchronized. please verify stream fps."

Can anyone help?
