What is the Difference Between DVD+R and DVD-R.

has been asked a billion times already (use SEARCH MESSAGES function next time please, is why it's there - lol)

Imagine if there were 5 different kinds of VHS tapes and they all looked identical but were not -- that is basically where the DVD standards world is right now. There are essentially 5 versions of writable DVD that you need to understand. They are: DVD-R, DVD-RAM, DVD-RW, DVD+RW, and DVD+R. The distinctions are actually based on how the data is written to and read from the disk, and this differentiation is difficult to translate to the physical world, however one example might be language.

Imagine if the entire world agreed on a single language for all written documents, say English. In the United States we would continue to create English documents and books in which one reads left to right. But another country might prefer to write and read English right to left. And yet another, top to bottom, and so on until the effect became that although all documents were created in a single language, it would be very difficult for a person from one country to read a document from another country. DVD recording is in a similar state of confusion. DVD is such a nascent technology that these issues have yet to work themselves out, so you have no choice other than understanding them all. One easy way to think about the formats is as 5 completely different kinds of DVD disks.

First, let's divide the formats up. The first thing to note is that DVD-R and DVD+R disks can only be recorded once. You only get one chance to record your DVD movie to this kind of disk It's like pouring cement, once it is done you'll need to destroy it to change it. Further, DVD-R discs come in 2 types: DVD-R(A), for "authoring," and DVD-R(G), for "general." Both DVD-R and DVD+R discs will play in most DVD players, even older ones. So if you put your movie on this kind of disk there is a high probability that it will play in your living room. However, DVD-R(A) drives can not record to DVD-R(G) disks, and vice versa.

There are also DVD formats that can be recorded more than once. DVD+RW, DVD-RW and DVD-RAM disks can all be recorded thousands of times. If you don't like how your DVD movie turns out, you can record a new version right on the same disk. These disks are more like painting a wall, if you don't like the color you just put on a new coat.

Each of these rewritable formats are a little different. DVD-RAM, for instance, was created for storage of computer data -- like backing up your hard drive. If you want to get a DVD writer to back up computer data, DVD-RAM is a solid option. However, if you plan to make your own DVD movies, one of the other formats may be better suited for that activity. Most DVD players can't play DVD-RAM disks.

The DVD-RW and DVD+RW formats are both good for making DVD movies but are essentially engaged in a Beta versus VHS-type battle. The consumer market will ultimately determine which format wins or they end up combining into a single standard, but it is important to understand that neither is yet a universal standard. Another thing to note is that many DVD players won't play any kind of rewritable disk. Most of the newer players will play these kinds of disks, but if you have an older DVD player it may not. In general, the newer your DVD player, the more likely it is to play all the recordable formats. There are web sites like Apple.com, HomeMovie.com and DVDplusRW.org that list compatible players and formats, but these are not unabridged resources either. Use them as a general guide.

Hi there Andy, it's me again -

We have got to talk you into reading some of these threads. You'll have a laugh reading some of this stuff and you'll learn a ton-'O'-STUFF too.

The stuff herbsman didn't tell you is a DVD-5 is < 4.36GB in size and can be backedup without compression While a DVD-9 is > 4.36GB.

Now there little fellow, off ya go, stay in this forum and pick a few threads and read - you'll pick up so much you'll save a bunch of mistakes and save me some typing too -

The thing about reading - the answers to your questions will mean a lot more because you'll have a bit of background )

Later there Guy,

Pete
