It doesn’t work with general ASR, it works for some shows but it doesn’t work for certain shows. Also if it is a movie, for example more than 1 hours, Subtitles are not in synced correctly. It cuts it 1 second early, if it is short series then 0.2 second early. It cuts the subtitle sentence while audio is going. It drives me nut. I mean why does it always have to be some kind of bug most of the time.
1 second negative delay example:
Chicken Run movie [Dutch ASR]
Asterix Secret of Magic Potion [Dutch ASR]
Orion and the Dark [Dutch ASR]
I can’t watch these three because of early cut of subtitles.
