[HELP] Error adding subtitle with speed change

[StoneCold]

Settings seem to be fine.
When stretching idx/sub-subtile Hybrid only takes the idx files and copies it's content and adjusts the time codes, in your case by a factor of 25/23.976=1.0240.., saves a new subtitle file and copies the sub file.
Background info: the idx file contains the location of the subtitles inside the sub file and the time code when to show it, the sub file contains the subtitles.

Looking at the calls, Hybrid uses:

I see that sox uses a factor of 0.95904000 (23.976/25) instead of 1.0240.. (25/23.976) that the subtitle stretching is using. So either one of them seems to be mixed up.

Is it only the subtitles or does the audio also go out-of-synch with the video?
If one of them is correct I can adjust the other to use the same stretch factor.

The audio is perfect, confirming it is only the subtitles that go out of sync.
