I just finished creating my own translation of a French movie. I created the subtitles and tried to mux the components together with IFOEdit. When I view the results in VLC however, the subtitle option is not present.
In fact, the results seem to be quite corrupt since opening it in DVDShrink, CloneDVD2, etc. doesnâ€™t register the movie properly (eg length of zero, no audio detected, etc.)
If I mux it with MuxMan using the same components, it seems to work correctly, except that the audio is no longer in sync with the video, they are too early (the subs are in sync with the out-of-sync audio); it does not happen with IFOEdit.
