DVD for Rent 1．A pay-for -play system
for video DVD (digital versatile disc) will emerge by summer as an alternative,
and possibly a competitor, to the DVD format currently available.

available initially from Disney, Dreamworks, Paramount, and Universal, growing
to 500 titles within a year. Most of these will be released in the 4:3 pan-and-
scan mode rather than in the 16:9 letterbox format. Other filmmakers have yet to
