Q & A

• What is a DVD? – DVD, or digital versatile discs, are similar in size and appearance to CDs. However, a DVD disc can store anywhere from 4 to 30 gigabytes of data versus the 700 megabytes on a CD.

• What is a DVD region code or country zone? – Region codes, also called country code, was devised by movie production companies to prevent a particular DVD disc from one zone to play in a DVD player or reader from a different zone (e.g. a DVD from Europe will not play in a DVD player intended for use in Asia). This is to prevent piracy of the contents of the DVD before it is officially released in that specific part of the globe.

• What is the difference between DVD-R and DVD-RW? – DVD Recordable will only allow a DVD recorder or burner to only burn data once on a disc. A DVD-RW will allow multiple writes and erases of data. The concept is the same for CD-Rs and CD-RW discs.

• Can my computer use DVDs? – As long the computer is equipped with the appropriate DVD reader drive, it can read data from DVD discs and even play DVD movies and audio.

• Can I make my own DVD movies? – Yes, using a DVD recorder or burner and software like Apple's iDVD, you can make home-made DVDs that can be quite similar to commercial DVDs. However, not all consumer DVD players might play the disc due to format conflicts. You must compatible media and equipment in order to view your movies.

• What is a DVD Player? – a consumer device that works similarly to a VCR. It plays DVD movies and audio, and most often times also reads your standard Audio CDs, Video CDs, and MP3 CDs.

• Are DVDs better than CDs for use on a computer? – In most cases the answer would be yes, citing the storage capabilities of the DVD against the CD. However, as is the case with DVD movies, compatibility is still an issue with most buyers. Admittedly, using DVD as a storage medium for use in a computer is still more expensive than using a CD-R/RW, but with prices of DVD recorders and media going down every month, the choice becomes more of preference.

• Can my CD player read DVD discs? – No, you will need a DVD player or reader in order to use a DVD disc.

• Can my DVD player read my collection of Audio CDs? – In most cases yes, DVD players and readers can read CDs quite well. The only exception might be the first iterations of DVD readers that came out in the late 1990s, these can only read DVDs. However, nearlly all DVD players in the market today are backward compatible with CD, CD-R, MP3 CDs, Video CDs, and CD-RW discs.
