And if your talking about DVD recordable formats they come in many more
flavors than 2.
There are DVD-RAM, DVD-R,  DVD-RW, DVD+R,  DVD+RW, DVD-R(A) plus several
other less
mainstream formats.

DVD+RW is an erasable format using phase-change media , and DVD+R is a
write-once variation of DVD+RW using
dye-based medium. The DVD-R is the most compatible format DVD-R does not
directly support CSS, regions, and Macrovision, but the newer encoding
DVD-R(A) does.

In short the recordable DVD compatibility market is a mess right now.  If
you have a recorder check the manual
for compatible media.
