A suggestion for everyone willing to adjust, correct or convert subtitles: use Subtitle Workshop for it all. Just today did I discover, after having already used SW for everything else, that you can also convert your subtitles with it. In my case I had a .sub file and I needed it to be .srt. After loading the file in SW, just pick "Save as", select your file type and it will convert your file to whatever you want. As simple as that. Go for it!
1. Download Subtitle Workshop at http://urusoft.cjb.net/ 2. Best is to use .srt format. (Save as SubRip when using SW)
