Suffit de lire la FAQ de leur site :
"Q: What is Divx?
A: Divx is a home video system, based on DVD, with a heavy emphasis on rental. It consists of three parts: a central billing system, similar to that used by pay-per-view satellite; specially-formatted DVD-ROM discs, of which there were two physical types, rental and Gold (never offered to the public); and special DVD players with the ability to decode Divx discs, built-in modems for communicating with the central billing system, and menus for purchasing Divx products online. Playback of Divx rental discs requires the support of the Divx central billing system, which was scheduled to be shut down on June 30, 2001. All Divx accounts were set to expire on July 7, 2001, after which players were directed to communicate with the billing system for final decommissioning."
