DVD-R and DVD+R are derived from CD-R format. DVD-R is the direct successor and there for older than DVD+R. Not all DVD players play both DVD-R and DVD+R. Check your instruction manual to see which yours is capable of using.

The differenced between DVD-R and DVD+R are the price, the format and ability to rewrite over the data, and the way the recorder manages defects. Also, DVD-R is offially approved by the standards group DVD Forum, while the DVD+R are instead supported by the DVD+RW Alliance.

A DVD-R is in a format that's compatible with the older version DVD players, and a DVD+R is in a format that's compatible with most, but not all newer DVD Players. Once the discs are recorded on, the information CANNOT be deleted, or changed.

Why then does it say on the DVD container in front of me DVD ReWritable? add a comment

to Goosebeat: REwriteable DVDs are another subclass... not all blank DVDs are rewritable, in fact, most are not. I don't think the data is as secure on a rewritable DVD, so if you want your data to last a long time, you are best using a "WORM" disc. add a comment

The two types of DVD storage hold the same amount of data but store it in different formats. DVD+R's are a more reliable technology due to minor updates from DVD-R but, overall the users will not be able to notice any differences in the technologies.
