Not sure if I’m naming the issue correctly but the problem comes from making an archive of a bluray that has the multiple mts files. Read about ClownBD and how you can use it to make one big file out of multiple MTS’s. Seems like there should be a way to do that with DVDFab.
I get an almost indiscernible pause when the media player goes from one of the mts files to the next. Just enough that you say to yourself, “Hey, did that pause…” because the playback is back and running as it should.
