Detecting one season but not another (1 Viewer)

[Darrin2101]

Can anyone explain why it will detect
Doctor Who s10e01 The Three Doctors.avi but not
Doctor Who s21e06 The Caves of Androzani.avi
both of which are in the same folder

Hi, sorry to take so long, I must have missed your message.

The problem lies in the default regex expressions, which assume season numbers don't go that high.

If you change the following expression:

^.*?\\?(?<series>[^\\$]+?)(?:s(?<season>[0-1]?\d)e(?<episode>\d\d)|(?<season>(?:[0-1]\d|(?<!\d)\d))x?(?<episode>\d\d))(?!\d)(?:[ .-]?(?:(?<episode2>\d\d(?!\d))|E(?<episode2>\d\d)|(?:\d\d|(?<!\d)\d)x?(?<episode2>\d{2}(?!\d)))|)[ -.]*(?<title>[^\\]*?(?<HR>HR\.)?[^\\]*?)\.(?<ext>[^.]*)$

to

^.*?\\?(?<series>[^\\$]+?)(?:s(?<season>[0-3]?\d)e(?<episode>\d\d)|(?<season>(?:[0-1]\d|(?<!\d)\d))x?(?<episode>\d\d))(?!\d)(?:[ .-]?(?:(?<episode2>\d\d(?!\d))|E(?<episode2>\d\d)|(?:\d\d|(?<!\d)\d)x?(?<episode2>\d{2}(?!\d)))|)[ -.]*(?<title>[^\\]*?(?<HR>HR\.)?[^\\]*?)\.(?<ext>[^.]*)$

Let me explain the change. The default expression assumes only season numbers from 0 - 19 are valid, as most shows do not have more seasons. This helps a bit to limit false positives. However with the above change, you tell it that season numbers from 0 - 39 are ok.

"[0-1]?\d" means look for a single or double digit number, where (if double digit) the first number can have values between 0 and 1. (note the \d is the same as writing [0-9] and the ? after [0-1] means it doesnt have to exist, but if it does, limit to the before mentioned). If you change that to 3, it will accept numbers between 0 and 3 (in your case 2 would also work).

Note I do not recommend changing the second season capture group in this regex (the one that looks for eg. 1101 as season 11 episode 01) because alot of things will have a year in its name, such as specials (2006, etc) so you might get a high number of false positives.

Hope this helps.

Edit: there is another regex in by default which has this limit, but you can change it if needed in the exact same way.
