What is DVD and Why DVD is Popular

DVD is an optical disc technology with a 4.7 gigabyte storage capacity on a single-sided, one-layered disk, which is enough for a 133-minute movie. DVDs can be single- or double-sided, and can have two layers on each side; a double-sided, two-layered DVD will hold up to 17 gigabytes of video, audio, or other information. This compares to 650 megabytes (.65 gigabyte) of storage for a CD-ROM disk.

DVD uses the MPEG-2 file and compression standard. MPEG-2 images have four times the resolution of MPEG-1 images and can be delivered at 60 interlaced fields per second where two fields constitute one image frame. (MPEG-1 can deliver 30 noninterlaced frames per second.) Audio quality on DVD is comparable to that of current audio compact discs.


  • DVD-Video is the format designed for full-length movies that work with your television set.
  • DVD-ROM is the type of drive and disc for use on computers. The DVD drive will usually also play regular CD-ROM discs and DVD-Video disks.
  • DVD-RAM is the writeable version.
  • DVD-Audio is a CD-replacement format.
  • There are a number of recordable DVD formats, including DVD-R for General, DVD-R for Authoring, DVD-RAM, DVD-RW, DVD+RW, and DVD+R.

DVD was originally said to stand for digital video disc, and later for digital versatile disc. With the coming of 2014, new DVD releases never take a breather, and even the shortest month of the year will have plenty of popular or critically acclaimed movies that screened in theaters last year hit the retail market.

Since DVD is more and more popular nowadays,  DVD-related multimedia software is plays more and more important role in our daily life. Here, Pavtube DVDAid is my first choice because it converts all my DVD for playing in a more convenient way without bothering to carry the DVDs. Pavtube determines the correct format/file and combines for main movie automatically. Great! Easy!

And besides that, with the Pavtube new official website being released, there are more new money saving software bundles like: DVDAid($35) + DVD Creator($35) = Only $35.9, Save $34.1, which means you can rip DVD to portable devices for on-the-go DVD movie enjoyment as well as get all your video files into playable DVD for entertainment. Really wonderful enjoyment!
