Positives:

-Standard DVDs are not in high definiton format and are only half the quality of an HD DVD.

-HD DVDs are in high definition format and obviously present a high definition picture.

-DVDs are made up of about 345,000 pixels.

-HD DVDs are made up of 2 million pixels, creating a clearer picture.

-DVDs have the ability to hold several extras.

-HD DVDs will potentially have the ability to hold three times more extras.

-DVD extras, such as director commentaries, are heard while the movie is playing.

-HD DVDs will be more interactive, allowing the commentary to be seen in a separate overlaying box on the screen while the movie is still playing in the background.

-DVDs, typically, only contain one movie.

-HD DVDs, presumably, could contain a trilogy of movies.

-Regular TVs without HD capabilities will not be able to play HD movies.

-Sales of HD TVs have increased over 60 percent since 2004.

-Standard DVD players will also not be able to play HD DVDs.

-HD DVD players will be able to play both standard and HD DVDs.

-Standard DVDs will look significantly better on new HD DVD players.

-HD DVDs will look five times better than that.

Negatives:

-Regular DVDs range in price anywhere from $15-$30 (depending on point of purchase).

-HD DVDs are will range about $5-$15 more (depending on point of purchase).

-Regular DVDs are released to work on virtually any regular DVD player.

-HD DVD and Blu-ray DVDs are backed by different companies, meaning some movies will only be available through HD DVD, while others will only be available through Blu-ray.

-Regular DVDs are released, once again, to work on basically any regular DVD player.

-HD DVDs will not work on Blu-ray DVD players and vise versa, which means until a DVD player is made available to play both formats, consumers may be forced to buy two different DVD players.
