HP has so far only been selling
single format DVD+R/RW writers but in the new dvd420i, dvd420e and dc4000 DVD
writers HP has also added support for burning the DVD-R/RW format. The dvd420i
is an internal IDE version, the dvd420e an external USB 2.0/firewire version and
the Movie Writer dc4000 is an external USB 2.0 version with built-in analog
video capture.

It clearly looks like most
companies now have realized that many consumers want to be able
to burn both DVD+R/RW and DVD-R/RW although I'm not sure if HP will
start shipping its PCs with DVD±R/RW drives too or if the new dual format drives
only are intended for the retail market. It also looks like the upcoming
HP dvd500i (a dual layer writer?) might only support the DVD+R/RW
format.
