DVD, digital video disc, or digital versatile disc, is a form of storage media based on the compact disc. It is a larger and faster form of a CD holding video and audio along with computer data.

A DVD can store six times more data than a CD. There are various companies producing DVDs, from Toshiba and Sony to Philips and IBM. The 12 cm type is a standard DVD and the 8 cm variety is known as a mini DVD. The capacity of data storage is measured in terms of gigabytes as they term it. A Dual layer disc differs from its usual DVD counterpart by employing the second physical layer within the disc itself.

They can be either video or audio. The DVD video is a standard for storing video content on DVD media whereas the audio is a format for delivering high fidelity audio content on a DVD. They can be recordable and rewritable as well. They have to be configured that way. They are processed and are ready as per the demand of the customer.

DVD MP3 is the newest form where only digital audio files in the MP3 format are stored. Not all DVD Players can play these discs. A DVD player can play a CD but a CD player cannot play a DVD or MP3. Earlier 'DVD duplication' or 'burning' was expensive and required skilled persons for doing it. But the people are well acquainted with the ripping software nowadays, and manage it on their personal computers.

The production of DVD requires an authentication to be produced. It needs to undergo certain rules and processes to handle the same. Fake and Illegal DVDs are flooding the markets of Asia, Latin America, and some African countries. Some security measures are there that can be applied today for stopping this. The copy prevention mechanism can prevent illegal copying and replicating of original copyrighted materials.

There are competitors in the market today. They have original production at a high price but unfortunately, a rival production may offer the same DVD as a home production at a lower price as well as in the original form.

The main points which must be kept in mind while choosing the quality for a DVD are better image and surround sound capture. It should have the ability to record live shows while playing back video content recorded earlier.

We must always be aware of the format of the DVD and its storage capacity. The number of recording hours must match our requirements. We travel with the discs so they must have proper connectivity options enabling us to make it portable. Due to its larger storage capacity the cluttering of CD and CD boxes have disappeared. A DVD rip can be of varied size but the most popular is 700-800 MB which means at least five full feature films can be included in a blank DVD.
