    I want to apologize if this question has been asked before! I just bought a new DVD burner. Can someone explain all the different DVD formats. Thanks!

    more specifically...

    DVD-R and DVD-RW
    DVD-R/W was the first DVD recording format released that was compatible with standalone DVD Players.
    DVD-R is a non-rewriteable format and it is compatible with about 93% of all DVD Players and most DVD-ROMs.
    DVD-RW is a rewriteable format and it is compatible with about 77% of all DVD Players and most DVD-ROMs.
    DVD-R/W supports single side 4.7 GB* DVDs(called DVD-5) and double side 9.4 GB* DVDs(called DVD-10).
    These formats are supported by DVDForum.

    DVD+R and DVD+RW
    DVD+R/W has some "better" features than DVD-R/W such as lossless linking and both CAV and CLV writing.
    DVD+R is a non-rewritable format and it is compatible with about 87% of all DVD Players and most DVD-ROMs.
    DVD+RW is a rewritable format and is compatible with about 77% of all DVD Players and most DVD-ROMs.
    DVD+R/W supports single side 4.7 GB* DVDs(called DVD-5) and double side 9.4 GB* DVDs(called DVD-10).
    These formats are supported by the DVD+RW Alliance.

    DVD-RAM
    DVD-RAM has the best recording features but it is not compatible with most DVD-ROM drives and DVD-Video players. Think more of it as a removable hard disk. DVD-RAM is usually used in some DVD Recorders.
    This format is supported by DVDForum.

    Also, the + camp is in the process of adding dual layer recording. Current +R drives will not be able to do it, though some may be able to with a firmware update. As of now, no -R technology developers have demonstrated dual layer recording.
