In the "old days" before the industry was standardized there were several technologies for writing and re-writing DVD's so you had to know if your specific DVD writer was a + or a - type if you wanted to burn "multisession" (burn some files now and later burn some more) Any modern DVD writer could not care less so you can use either (but if you play the DVD back on an older unit you might have problems.

A DVD+R can only be recorded once. A DVD+RW can be recorded on multiple times until the disk is full. You add data to a DVD+RW, but you can't remove previously recorded data.
