Hi everyone!!
That can be so silly but it´s true, some Bluray disc movies (most of WARNER), have a hidden Audio and Subtitles Tracks inside the disc. I´ve put some Blurays who say on the back cover that have Japanese Audio track (in my case with HOME ALONE and LOST SEASON 1), but when you put in the home player or PC, this track don´t appear at any time. So, with the programs "MAKEMKV" and "DVDFAB9", i see that the same movie is repeated 2 or 3 times, and the audio and subtitles tracks are not the same. One of this movie copy are the hidden Japanese audio track.
Now o going to put all the covers of the Blurays i have that bring Japanese Audio track (putting or not in the back cover), and YES, i going to rip all but with big pacience because 1 movie rip takes more than 4 hours or encodings.
The movies (and series) are:
