I say, SubRip's nearing perfection, good job
One suggestion though, would it be possible to include a feature to be able to rip the colour codes of the subtitles too? If there's any interest for that kinda option, naturally, don't think this is much of an issue to most of the users. I just recently ripped the first subs (the colours identifying different people, which looks pretty confusing without the proper colours since the subs intertwined) in which this would've been a handy option.
