I disabled the Microsoft antivirus, but the problem is still showing. The first subtitle get extracted even if the dialog error box shows that Hybrid failed to extract the subtitle. The Hybrid GUI remain "frozen" and I have to kill the application, in this situation all the remaining subtitles are not extracted.
Then I tried to perform the following test:
1) I used "My MP4Box GUI" to extract the subtitles (see attached image)
2) I used MKVtoolnix GUI to convert the mp4 container in mkv. For some reason also this tool is unable to get the subtitles (but this is an old problem), so I had to add the subtitles extracted previously with "My MP4Box GUI"
3) I used Hybrid to encode the movie and in this case the subtitles get extracted correctly and the encoding completed successfully.
So it seems that the problem is related only to mp4 containers.
