Differences between DVD-RW, DVD+RW?

Can anyone explain the difference between DVD+RW and DVD-RW? I've never been very clear on this.

DVD+RW format can be created on a PC and is meant to be played back on most DVD players and DVD-ROM drives in PCs. DVD-RW offers compatibility only when discs are created using a special recording mode, which somehow limits the users editting capabilities. A third competing format, DVD-RAM, uses a disc in a cartridge, but supposedly works on a similar encoding process as DVD+RW, but the cartridge limits its usage.

The +R and +RW standards were created in part because some companies didn't think the -R/RW standard had sufficient error correction capabilities built in, so +R, and particularly +RW, have better error correction.

Also, the +R/RW discs supposedly have better compatibility with older standalone DVD players.

Ripped from a post in this thread:

DVD+R doesn't use pre-written blanks like DVD-R. This allows CSS header infomation to be written on DVD+R discs. One benefit of this is that the CSS header can be written to make DVD+R disc's compatible in older DVD players. (players that won't read a DVD-R)

DVD+RW has defect management and lossless linking. Lossless linking allows packet writing to not waste space. DVD-RW wastes alot of space when appending data. DVD+RW doesn't waste any space when appending data.

vcdhelp is good for something once in awhile

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 88% of all DVD Players and DVD-ROMs.
DVD-RW is a rewriteable format and it is compatible with about 69% of all DVD Players and 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 84% of all DVD Players and DVD-ROMs.
DVD+RW is a rewritable format and is compatible with about 70% of all DVD Players and 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. This format is supported by DVDForum.

Read our DVD Players Compatibility list to see what types your DVD Player supports. You find more detailed comparisons between the formats in the more info section here.

-R is better, get it :|
