What are the disadvantages of DVD?
• It will take years for movies, TV shows, other video programming, and computer software to become widely available. • Vagueness of spec and inadequate testing of players and discs has resulted in incompatibilities. Some movie discs don’t function fully (or don’t play at all) on some players. • It can’t record (yet). (See 1.14 and 4.3) • It has built-in copy protection and regional lockout. (See 1.11 and 1.10) • It uses digital compression. Poorly compressed audio or video may be blocky, fuzzy, harsh, or vague. (See 1.3) • The audio downmix process for stereo/Dolby Surround can reduce dynamic range. (See 3.6) • It doesn’t fully support HDTV. (See 2.9) • Some DVD players and drives may not be able to read CD-Rs. (See 2.4.3) • Current DVD players and drives can’t read DVD-RAM discs. (See 4.3) • Only a few players can play in reverse at normal speed. • Variations and options such as DVD-Audio, DTS audio tracks, and Divx are not supported by all players.
• DVD recorders are more expensive than VCRs. • DVD has built-in copy protection and regional lockout limiting playback in different countries and any duplication. • DVD doesn’t fully support HDTV. • There are some compatibility issues with recordable DVD formats, such as DVD-R, DVD-RAM, DVD-RW, DVD+RW, and DVD+R. How long do DVDs last? DVDs are read by a laser, so they never wear out from being played since nothing touches the disc. Pressed discs (the kind that movies come on) will probably last longer than you will, anywhere from 50 to 300 years. Will DVD replace VCRs? Eventually. DVD player sales exceeded VCR sales in 2001. DVD recorders will hasten the death of VCRs once the price difference is small enough. DVDs have many advantages over tapes, such as no rewinding, quick access to any part of a recording, and fundamentally lower technology cost for hardware and disc production. Some projections show DVD recorder sales passing VCR sales in 2005. Can DVD record from TV/VCR/etc? Yes
