I am writing an essay on video games and naturally I am referencing a number of them as examples. Since we are in Computer Science, we use the IEEE reference style and there is a section that specifically shows how should a computer game be referenced:
 The Hobbit: The prelude to the Lord of the Rings. [CD-ROM]. United Kingdom: Vivendi Universal Games, 2003.
So what type of entity do I use in Bibtex and which fields do I set?
Note: I am using the IEEEtr bibliography style in latex.
