Sorry, but sometimes you have to do other things than watching this forum.
Take DVD SubExtractor instead of subrip. You'll find it here: https://subextractor.codeplex.com/
This program has a better ocr than subrip.
It's easy to use and makes almost no mistakes. Just load your extracted bluray.sup or dvd idx/sub file and follow the instructions on the right side.
Then store the result as .srt
To rip subs out of a bluray or dvd there are many ways. Are you use windows, linux or mac?
