[QUOTE=eightysix;92295]Also, I have been reading a lot about movies with multiple .m2ts files that make up the main movie.
Almost every movie has multiple .m2ts files, but I have never encountered a situation where I would need to combine any. Have I been missing this in my backup projects? How will I know if I encounter one of these discs?[/QUOTE]Most main titles are authored as a single .m2ts file. Yet, there are many disks in which the main title is authored as multiple .m2ts files -- this is called seamless branching. This is often done to support multiple languages. A couple examples: Disney's UP and Prince of Persia.
If you are using DVD Fab to rip a full disk to burn onto BD-R, there is no need to be concerned. The confusion comes in when trying to just rip the main title and DVD Fab presents you with multiple main title selections. In that case you need to first play the disk in your BD player, select the title in your language from the menu and once the movie is playing, use the players OSD to see which title # is playing. Then you go back into DVD Fab and select that title # when you do the main title rip.
As in the case of a full disk rip, if you are using DVD Fab to rip the main title and burn to BD-R, you need not be concerned about seamless branching. Your BD player will read the playlist file which tells it the proper sequence of .m2ts files to play.
The only time you need to be concerned about seamless branching is if your intent is to use DVD Fab to rip the main title to your server or NAS unit for streaming playback over your network using a media player (this is what I do). Only the most expensive media players know how to read the playlist to properly sequence and play the multiple .m2ts files. The reasonably priced media players do not and only play .m2ts files directly. In that case you would need to stitch together the multiple .m2ts files when you rip a seamless branching title -- DVD Fab BluRay Copy does not do that. You would need to use a separate helper utility after DVD Fab, such as xxxxxx or xxxxxx, to stitch them together.
