Sorry for the delay, I have not been able to answer before.
I have a Mutant HD60 with Openpli 7.0 (stable) 20190617, It is the one that suits me best. I have also tried the newest but the same thing happens.
I have done the test in the channel "Movistar+ Estrenos" of satellite Astra 19.2 (Movistar Spain).
These are the subtitles that I activate (DVB):
I made a video but I can't upload links, I'm sorry. Basically in the video the subtitles appear very fast and at the wrong time.
I put another test but this time on the channel M+ Disney, when I activate subtitles (teletext) they work well:
Therefore, it seems DVB subtitles problem
THX and sorry for my English, is of google translator
