Fast-forward loses Audio sycn on PS4

[Mercury]

I just re-installed UMS using default settings and for most rips, I can't fast-forward without losing Audio/Video sync... It doesn't seem to matter which renderer I use, this almost always happens.I've been using UMS for a long time and this has been an issue for a long time. It doesn't seem to happen on old rips, but of the newer ones almost all of them have this issue.

Is there a solution to this? Sometimes even just pausing and unpausing makes the video crash and then when I resume I lose sync as well.

Any help would be highly appreciated, I use UMS and PS4 as my main platform and this is driving me crazy!

This seems mostly a bug on MEncoder, which is likely being used if there are subtitles involved. We can't know more without logs though.

I do use subtitles but I tried to go to transcoding and select FFMPEG for instance and it's the same on other encoders.

What logs would help you? Just a debug log from UMS? I can get that no probs.
