On December 1, 2002, a new code "v" specifically for DVD format videorecordings was implemented for the Videorecording 007 field subfield ‡e (007/04).

Use the new code "v" to identify all DVD videos. DVDs use the digital PCM (Pulse Code Modulation) technique to represent video information on a grooveless, smooth, round plastic disc. Most DVDs are 4¾-inch in diameter, although some smaller 3-inch discs have also been commercially produced. DVDs are usually identified by the term or trademark DVD, DVD VIDEO, or VIDEO CD (the standard compact disc logo with "DIGITAL VIDEO" below it). DVDs have been commercially available only since 1996.

A typical DVD will be coded and described as such:

007 v ‡b d ‡d c ‡e v ‡f a ‡g i ‡h z ‡i s
300 1 videodisc (99 min.) : ‡b sd., col. ; ‡c 4 3/4 in.
538 DVD, Dolby digital stereo.

The existing Videorecording 007 subfield ‡e value "g," previously defined as "Laser optical (reflective) videodisc," has been redefined more narrowly as "Laserdisc." Use code "g" only for videodiscs that use the analog PWM (Pulse Width Modulation) technique to represent video information on a grooveless, smooth, round plastic disc.

Laserdiscs exist in three standard commercially produced sizes: 12, 8, and 4¾-inch. The 12-inch discs are the most common, typically used for movies. They are usually identified by an LD trademark (with the phrase "LASER DISC" or "Laser Vision" below the LD trademark), LASER VIDEODISC, DiscoVision, LaserDisc, LaserVision, or similar phrase.

Much less common are the 8 and 4¾-inch discs. Typically used for music videos or other short video programs; these are usually identified by the term r trademark CDV (CD VIDEO), VSD (VIDEO SINGLE DISC), or LD (LASER DISC). These analog laserdiscs became commercially available in 1978, but production declined rapidly after 1998 because of the success of the DVD digital format. Do not use code "g" for DVDs.
