Hvad er forskellen mellem DVD-RW og DVD+RW

Hej
Jeg er ny i det med at brænde, og jeg kan se at der er 2 slags skiver man kan brænde på. Nemlig DVD-RW og DVD+RW hvad er forskellen mellem dem❓Er det lige meget hvad man bruger ?

Forskellen på de to typer brændbare dvd'er er at dvd+rw er et nyere medie end - mediet. Der er derfor også større sandsynlighed for at en dvd-rw kan afspilles i flere afspillere.

Hej med jer.
Jeg har selv stillet dette spørgsmål om fandt efter nogen søgen (debat fora under edbpriser.dk) et link der førte til dette:
DVD stands for Digital Versatile/Video Disc, DVDR stands for DVD Recordable and DVDRW for DVD ReWriteable. If you're familiar with regular audio/music CDs or regular DVD-Video discs, then you will know what a recordable DVD looks like. A recordable DVD stores up to 2 hours of very good quality DVD-Video, including several audio tracks in formats like stereo, Dolby Digital or DTS and also advanced menu systems, subtitles and still pictures that can be played by many standalone DVD Players and most computer DVD-ROMs. If you choose to lower the video quality it is possible to store several hours video on a recordable DVD using low bitrates and low resolution with video quality more like VHS, SVHS, SVCD, CVD or VCD. It is also possible to have up to 4.37* GB ordinary data or mix DVD-Video and data on a recordable DVD that can be played by most computer DVD-ROMs.
There are three competing DVD Recording standards, DVD-R/DVD-RW and DVD+R/DVD+RW have pretty similiar features and are compatible with many standalone DVD Players and most DVD-ROMs while DVD-RAM has less DVD Player and DVD-ROM compatibility but better recording features.
DVD-R and DVD-RW
DVD-R 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 80% of all DVD Players and most DVD-ROMs.
DVD-R and DVD-RW supports single side 4.37 computer GB* DVDs(called DVD-5) and double sided 8.75 computer GB* DVDs(called DVD-10).
These formats are supported by DVDForum.
DVD+R and DVD+RW
DVD+R is a non-rewritable format and it is compatible with about 89% of all DVD Players and most DVD-ROMs.
DVD+RW is a rewritable format and is compatible with about 79% of all DVD Players and most DVD-ROMs.
DVD+R and DVD+RW supports single side 4.37 computer GB* DVDs(called DVD-5) and double side 8.75 computer GB* DVDs(called DVD-10).
These formats are supported by the DVD+RW Alliance.
DVD+R DL
DVD+R DL or called DVD+R9 is a Dual Layer writeable DVD+R. The dual layered discs can hold 7.95 computer GB* (called DVD-9) and dual layered double sides 15.9* computer GB (called dvd-18).
DVD-R DL
DVD-R DL or called DVD-R9 is a Dual Layer writeable DVD-R. The dual layered discs can hold 7.95 com-puter GB* (called DVD-9) and dual layered double sides 15.9* computer GB (called dvd-18).
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 Re-corders.
This format is supported by DVDForum.

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

DVD Sizes
The DVD sizes can be a bit confusing. There are basicly 4 different DVD Sizes,
DVD-5, holds around 4 700 000 000 bytes and that is 4.37 computer GB where 1 kbyte is 1024 bytes* . DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Single Sided Single Layered. This is the most common DVD Media, often called 4.7 GB Media.
DVD-10, holds around 9 400 000 000 bytes and that is 8.75 computer GB. DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Double Sided Single Layered.
DVD-9, holds around 8 540 000 000 bytes and that is 7.95 computer GB. DVD+R supports this format. Also called Single Sided Dual Layered. This media is called DVD-R9, DVD-R DL, DVD+R9, DVD+R DL or 8.5 GB Media.
DVD-18, holds around 17 080 000 000 bytes and that is 15.9 computer GB. DVD+R supports this for-mat. Also called Double Sided Dual Layered.
* In the computer world is 1 KB data = 1024 bytes so 4 700 000 000 bytes / 1024 = 4 589 843KB / 1024 = 4482MB / 1024 = 4.37GB. See section 3.3 in the DVDDemystified FAQ here.

DVD+R/DVD+RW/DVD+R DL and DVD-R/DVD-RW exact sizes
DVD-R/DVD-RW = 4 706 074 624 bytes ( 4488 MB )
DVD+R/DVD+RW = 4 700 372 992 bytes ( 4482 MB )
DVD+R DL = 8 547 993 600 bytes ( 8152 MB )

.... ikke af særlig stor betydning.
Forskellen på + og - skiver er den måde data lagres på skiven. For dig som bruger er det stort set uden betydning, da både alm. data og film kan lagres og bruges uanset om du bruger + eller - skiver.
Det eneste du skal være sikker på er, om din brænder/læser bruger det ene eller det andet format (eller begge).
I dag kan langt de fleste DVD-brændere bruge begge typer, ligesom de fleste DVD-afspillere kan det. Der findes dog stadig brændere/afspillere som er dedikeret til det ene eller det andet format. Du må kigge i din manual og se hvad netop DIT udstyr kan bruge.
Husk at der også findes afspillere som IKKE er glade for at afspille hjemmebrændte skiver, ligesom der findes skiver af forskellig kvalitet. Det er ikke alle skiver der kan bruge i alle drev.
Godt nytår
