Yay, my time to jjoin in the regex  fun.

I  havent worked with regex for a couple of years now. So this should be a fun at it. I've read this thread and hope i get it now

My files are all named quite consistently... for the most part. I am having trouble getting it to distinguish between moves like this.

Wild.Wild.West.1999.DVDRip.XViD.iNT.CD1-JoLLyRoGeR : Title.Title.Title.YEAR.Quality.notuseful
Taken.WS.R5.XViD-PUKKA                                       : Title.QualityVariant.Quality.notuseful
Bangkok.Dangerous.R5.LINE.XviD-COALiTiON               : Title.Title.Quality.Quality.notuseful
Futurama.Benders.Big.Score.DVDRiP.XviD-OPT             : Title.Title.Title.Title.Title.Quality.notuseful (this is the most common naming format, or the first option).

Thats about all the variation i have in my files.

Is it easiest to just set my regex to read til it hits a predefined Quality type? I know all the values it will eventually hit (R5, R5.Line, DVDSCR, DVDRIP, AC3.DVDRIP, SCREENER, WS.R5, TC, TS, BDRIP)

Also, where does the quality of the file get read in, i dont see it as an option. Or does it happen somewhere else?

So something like...
(?i)^.+\\(?P<title>[^\\]+)[^\\]+(?P<year>(19|2\d)\d{2})   - This predefined one should catch the 1st option and im confident in that.

(?i)^.*\\(?P<title>.*)\\(R5|R5\\.LINE|WS\\.R5|DVDSCR|DVDRIP|etc|etc).\..*   - should be matching the 2nd/3rd/4th type? (i cant seem to tell if you need to add the \\ to escape a "." whilst inside the |...| areas)

Sorry to be a pain, i know how aggivating it is to interpret someones regex stuff. Also thanks for any help guys.
