For a computer, it costs more to make a cd-rom player these days
than a dvd player due to economies of scale.  There's a tremendous 
demand for DVD players in computers.  Cd-roms are being sold, in 
the meantime, to clear out the inventories while still charging the 
clueless a lot of extra money for the DVD.  You can buy a dvd drive
for peanuts ($50), and a sigma designs dvd decoder is about the same
amount, if you want to watch movies :-)

Future DVD players will have the DVD-Multi certification that's a new
part of the DVD Forum's standards.  That specifies that a dvd player 
with the DVD-Multi logo is guaranteed to be able to read DVD-ROM, 
DVD-Video, DVD-Audio, DVD-R, DVD-RW, and DVD-RAM.

Settop players won't be able to read DVD-ROM.  Writers will be able
to write DVD-R, DVD-RW, and DVD-RAM.  It's not clear what's going
to happen with DVD+RW.

The DVD Forum's DVD-Multi spec was derived from the Optical Storage
Technology Association's DVD-Multi2 from December, 1999.  That one
specified how DVD players would read CD-Audio, CD-ROM, CD-R, and CDRW.
I figure those will be included, though it may take three lasers to
do it all.

Regards,
Matthew

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
