MOVIE filenames:
For this example, I searched for Iron Man 2 on torrentz.com
In the first item on the list, the filename reads as such:
Iron Man 2 2010 DvDrip Eng FXG
Iron Man 2 = title
2010 = year of the movie's release
DvDrip = Release Type/Quality of Movie
Eng = language (English)
FXG = the name of the person(s) who uploaded the file
So in short, this is usually how most movie/tv show torrents are labeled.
(Title) (Year) (Release Type/Quality) (Language) (Uploader)
Sometimes you might see a label such as XviD. This is simply a type of video codec used to create the movie file. You do not need to worry about this too much.
