What are the disadvantages of DVD?

 

·         Vagueness of the DVD specification 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.

·         DVD recorders are more expensive than VCRs.

·         DVD has built-in copy protection and regional lockout.

·         DVD uses digital compression. Poorly compressed audio or video may be blocky, fuzzy, harsh, or vague.

·         The audio downmix process for stereo/Dolby Surround may reduce dynamic range.

·         DVD doesn't fully support HDTV.

·         Some DVD players and drives can't read CD-Rs.

·         Some DVD players and drives can't read recordable DVDs.

·         Most DVD players and drives can't read DVD-RAM discs.

·         Very few players can play in reverse at normal speed.

·         Variations and options such as DVD-Audio, DVD-VR, and DTS audio tracks are not supported by all players.
