Well i hope i make myself comprensible, english is not my natural language, i been authoring some dvds with dvdshrink and deleting some audio and subtitles tracks to get more space room for the main movie, well when i playback the movie some labels that inform the kind of audio (example Spanish audio 2.0) or subtitle (english) doesnt show in the screen but they did work and begin to play the audio or show the subtitle, its not a big deal because they work, but just wondering what happend, i just follow the guides for dvdshrink and they dont mention something like this, thanks folks..
