I have subtitles for Dr. Who. All are working correctly, but one. When the subtitles are on the screen (of tv), there are numbers and letters above the words. Example: X 1:170 X 2:59 Y 1:474 Y 2:254 "Summon the steward! I'm afraid the steward is dead" That is what I see on the screen. The subtitles for the videos before and after that are fine. Why is this happening? And how can I stop the letters and numbers from showing up? I hope someone can tell me why this is happening. I would appreciate any help anyone can give. Thank you.
