DVD+ or - R are write once only or Read only (once written). DVD + or - RW are ReWritable.

I suggest you Google them for more information.

Is there a difference between DVD+R and DVD+RW?
Seems when I burn to a DVD+R I'm unable to erase the disc. I am told that
it is Write-Protected by Vista Basic when I try to re-format it.
But I'm able to erase and re-format the DVD+RW.
