The thing is, if a certain device has trouble play-backing a movie with VobSub subtitles, and that movie happens to be a rare one, which means it wouldn’t be the best idea to search for its SRT subtitle online as a replacement, then converting VobSub/SUB IDX to SRT might be your last resort. Speaking of which, I must mention SUB subtitles. Compared with the former, VobSub is just the repacking version with additional cue time information stored in .idx file. And the VobSub to SRT conversion it’s pretty much the same as what we’ve done at SUB to SRT. For those who’ve missed it, I’ll show you the exact procedures right below.
