< Opinie na IMDB to RARBG Torrent Search
For 1337x and RARBG Index it uses the movie title but for TorrentGalaxy it uses the id because it's more reliable.
However, if you want to use the name you can modify the code on line 109 and change id to name (like on lines 110/111).
Would it be possible to have the script get the page title instead of the movie ID? Cheers!
