Put briefly, Divx discs are $4.49 movies on digital video discs with an additional encryption scheme. Divx discs require a Divx player (a.k.a. "DVD player with Divx enhancement"), and can be viewed for one 48-hour period, beginning when the disc is first inserted into the player. Divx movies rarely come in widescreen versions, and they offer none of the "extras" that are commonly found on open DVDs. Because the consumer owns the Divx disc, he/she never has to return it, and he/she can watch the Divx movie again by paying $3.25 for another 48-hour viewing period.
