What are the disadvantages of DVD?

Despite several positive attributes mentioned above there are some potential disadvantages of DVD:

• It will take years for movies and software to become widely available.
• It can't record (yet).
• It has built-in copy protection and regional lockout.
• It uses digital compression. Poorly compressed audio or video may be blocky, fuzzy, harsh,
• or vague.
• The audio downmix process for stereo/Dolby Surround can reduce dynamic range.
• It doesn't fully support HDTV.
• Some DVD players and drives may not be able to read CD-Rs.
• First-generation DVD players and drives can't read DVD-RAM discs.
• Current players can't play in reverse at normal speed.
