About 7 days ago, out of the blue all the sudden lots of my IPTV channels started having Closed Caption on them.. I have no clue why.. Some channels have it, some dont. Some that do have it sometimes dont.. Its driving me Nuts.. Anyway to turn this crap off? I reported it to my IPTV provider but they said not on their end but something on my End.. I use a Mi box with SBT emulator Pro and there is a subtitles option but when I try and set it to "None" nothing happens..
I also have this problem with stb emulator pro - as you say, trying to toggle the "closed captions" to "off" doesn't work for some reason. Let me know if you find a fix, for now I have changed my media player from "auto" to "ljk" and that seems to have gotten rid of the captions, but there must be a better way. I also have a friend who downgraded to a previous version of stb emu pro, and this fixed it for him as well.
I swear that some people at /r/fabIPTV had this same problem and fab did something at their end to fix it but I could be wrong. Maybe the fab mods could comment?
Look into settings, try to find the option of Teletext and deactivate it.
