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 none rewriteable format and it is compatible with about 85% of all DVD Players and DVD-ROMs.
DVD-RW is a rewriteable format and it is compatible with about 65% 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 none rewritable format and it is compatible with about 85% 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.

In addition:
All DVD-ROM drives can read both discs. "Plus" writers can _READ_ "minus" discs and vice versa.
And the biggest difference is price -- minus discs cost less.

But, why there is Minus and Plus in the first place? Just interested.
Plus doesn't seem to take huge advantage on minus. or there is something I missed?
Thanks

Money. HP, Philips & co didn't want to be the paying party in the licensing fun -- they don't own patents used in "minus" technology -- so they developed their own technology and now squeeze licensing income from other companies who use their "plus" technology. Simple as that.

Which will go more common in the future?
Or two kinds just going to be developed in their own ways?

No one knows. My guess is that both formats will exist till the end and the thing that will kill them both eventually will be some totally new format, probably some blue-laser DVD-type of technology.

So i take it for purposes of coping movie dvd's to dvd... -R is just as good as +R format. (assuming the stand-along compatiablity issue is the same for both types for a particular user's system?) yes?

another question...
Is the format -R +R the same format with the difference being the media characteristics hince the need to have different media sold.
I was thinking that the format, if it could be read by a stand alone player, it would "look" the same to it and it doesn't matter if its -R or +R assuming the laser heads can pick up the signal on the disk.
is that how it works?
Thanks,

Pretty much yes, the data is organized slightly different and the mechanics of the disc itself are slightly different in + and -, but your assumption is pretty much correct, yes.

thanks.. when you say "mechanics of the disc" are a little different, is the disk heavier or spin different, is that what is meant by that? I know about CLV & CAV difference support between the formats.. or is that the difference you mean?
BTW: If you copy a disk to disk does the loosless linking technology still come into play for this? Would that make the +R format able to detect errors more so then the -R format? (or would +R just be able to stop errros from occuring in the first place?)
thanks,

By mechanics, I meant the data surface will be burned in different way. And AFAIK, if you copy 1:1 DVD-Video to either format, the error correction and such will be identical, regardless of the used standard, so you don't achieve anything by using + or - compared to the other disc.

Actually, not all dvd roms can read all the formats. My TOSHIBA second generation won't do rewrites. It just chokes on them. Now possiby all third generation on up can handle them fine.

That is more about the difference in physical disc itself, but the data itself is stored identically to all four formats and therefor there's no difference in terms of quality or structure between different recordable DVD formats when speaking of DVD-Video.

I guess that is the big assumption... "if the laser heads can read the data..." then the data is structured the same... it is not a compatiablity issue... more of a physical one between the laser heads and the media as opposed to the a structural difference like say the difference between NTFS and FAT in disk structure analogy... yes?
if so it looks like everyone is saying the same thing more or less. yes?
The bigger point I suppose I was trying to test is that if and its a IF, but if my stand alone dvd-drive can read -R and +R media... why use +R media when watching dvd standard movies (backup copies of course) ? If I can use -R media just as well as +R, why not just go with the -R media which is cheaper... all things being equal?
I do see a difference for using +R over -R in certain applications which would use CAV or CLV but that's not an issue on movies already created, yes? I mean, once it is burnt, it is burnt doesn't matter what it did to get there, yes?

Sort of, although DVD+RW's data mode is totally different story, but let's not get into that one, since we're talking about DVD-Video discs in here ;-)

You're exactly correct. If your player supports both standards, there's absolutely no point using the "plus" media, as it costs appx 2-3 times more than "minus" media and doesn't offer anything that minus doesn't in terms of DVD-Video.

Now I know how to get my questions answered. Just write in capitals and put the word "Hell" in there!!! Just being a smartass, dRD. (Dumbass?) I thought this whole issue of DVD-/+R was complicated, now I KNOW it is. But the important part is that if it doesn't impact on viewing quality, who cares, just go for -R 'cos it's cheaper.
Peace out.

not sure about the dumbass stuff... but since we are on the subject of media.. and I do understand there is a link about media somewhere... what -R media is a good balance between cheap and performance? (with emphasis on flawless performance. :) )
ok so there are several factors but what price range should I try to buy the media for without wondering/worring if the blue dye will melt off in a few months or something. ??? 0.50 per disk, more or is it less?
Thanks!
