Through making an application I found it was incredibly hard to find the ID numbers netflix assigns to their TV shows and movies. So, after about a week, I now have a database of every movie and tv show on netflix, and thier corresponding ID. Additionally, In the folder Ndatabase, there are also .json files whose file names correspond to the ID's from showtitles.txt. These contain complete info on every episode in every season of every show on Netflix.
Additionally, I have found that the URL scheme netflix uses to open certain videos in their iOS app is as follows: nflx://www.netflix.com/Browse?q=action%3Dview_details%26movieid%3DIDNUMBER or, to play a video: nflx://www.netflix.com/Browse?q=action%3Dplay%26movieid%3DIDNUMBER
Replace IDNUMBER with your movie or episode's ID
