Jewel cases may be used to prevent scratching of DVD-ROMs. Recordable DVDs are still typically available wherever music and movies are sold, however, including office supply chains and discount marts. For home audio and data storage, flash drives have become quite popular.
An increasing number of movies and TV programs are being released on Blu-ray™ discs, which have a higher capacity and quality. An audio DVD can hold just over an hour of multi-channel music at 192 kHz, the highest bit rate about two hours at 96 kHz and close to seven hours at the standard CD sampling rate of 44.1 kHz.Ĭassettes, video cassettes, and laser discs have become legacy technologies, and DVDs may be headed in the same direction.
For this reason, people are moving towards DVDs to store music. This is still a big improvement over CDs, however, which use 44.1 kHz, 16-bit sampling to produce audio. By comparison, standard DVD players use 96 kHz, 24-bit DACs. For home theater systems, shoppers should look for models equipped with a 192 kilohertz (kHz), 24-bit digital/analog converter (DAC) for true theater quality. When purchasing a DVD player, consumers should be sure to get one that can play all DVD-ROM formats, including double-sided, double-layered discs. DVDs are much more compact and easier to store as well, and players can usually also play CDs. It can also hold more information in a higher format, and a viewer can skip to specific scenes without the need for fast-forwarding or rewinding.
Under normal conditions, a DVD remains error free and consistent, regardless of the amount of times it is viewed, while a video tape stretches with wear and eventually needs replacement. For one, it stores data in digital form, while the video cassette uses less precise analog technology.
If it doesnt play, or if you want to play a disc that is already inserted, open Windows Media Player, and then, in the Player Library, select the disc name in the navigation pane. Typically, the disc will start playing automatically. The DVD-ROM has largely replaced the video cassette, being far more efficient and superior in most respects. Insert the disc you want to play into the drive.
