I see so many 2-4x dvd+r  or 1-16x dvd+r what is the difference?
87551
all those x's are speeds, 1-16x means that the disc supports burn speeds of 1x, 2x, 4x, 8x, 12x, 16x. Your write should also support those speeds else it will burn with a slow speed.

CD-r burns on the bottom of the disk, where a CD+R burns on the top.  There is really no difference in terms of use.

Most DVD writers will burn either and most DVD players will play either. I use +R but I have no real reason except they always work wherever I want them to.

Background:\n\nDVD-R and DVD+R are both single layer, although they are composed of 2 disks glued together; one for recording and the other as a stability layer. DVD+ has the ability to support dual layer disks, but they must have DL after it (i.e. DVD+R DL).  Dual layer DVDs hold 8.54 GB and DVD's hold 4.7 GB, which is about 4.38 Gigs on a computer because DVDs are measured differently. DVDs spin about 3 times faster than CDs, allowing a larger data rate, making them optimal for video.  By the way, DVD means Digial Versitile Disk.\n\nAnswer:\n\nThe DVD- format was set up by a group as the "standard".  DVD+ disks are rivals of the DVD- format, and therefore are not considered as an official format, but they work in most situations.  The + disks are engineered differently and are considered track better and write better.  Again, the + system will SUPPORT Dual Layer, but it must be labeled with a DL.

The  +/- sign is for the Dvd writer.If it displays both  signs it takes both plus and minus dvd's and cd's\nRW means re-writeable disc it will say either+format or -.on the disc

It is dual layer dvd, meaning you can burn 2 layers on certain types of dics and instead of fitting 4.7 gb's you can fit 9.4gb.  Pretty nice to have!

Hi, \n\nfirst of all, don't confuse DVD-ROM speed with CD-ROM speed, the notation is different.\n\nCDrom  speeds 1X, 2X, 4X etc is the number of times the drive is than the single-speed (1x) CD-ROM player.\n\n1X CDRom drive gives a data transfer rate of 150 kilobytes per second. (1x speed rating for DVDs 1.32 megabytes/s.)

It is a format difference originally between manufactures. Now most DVD players will read either +R or -R. There is supposedly a slight useage edge for -R but ability to read is what is important. I record all my DVDs in +R and I never have a problem playing them in any DVD player. \n\nMy computer burner will burn either format but I just started using +R and that is what I usually buy.\n\nNeither a +R or a -R are rewritable. For that you want a +R-RW or a -R-RW.

It's just two different formats of DVD media.  If you plan to use either make sure you're DVD writer is compatible with the type you plan to use.  Most of the newer drives can let you use both types. They will say something like DVD±R (DVD +/- R).\nCheck out the two links below.

CD's dont have the plus and minus conventions, only DVDs do.  This is because, there are two competing groups that manufacture DVDs, the "plus" forum headed by HP, Dell, etc. that manufacture DVD+RW, DVD+R, etc. and the DVD Forum headed by Pioneer which manufacture DVD-RW, DVD-R, etc.\n\nHence, CD-R and CD-RW are valide conventions, CD+R and CD+RW are not.

The 1-disc version has nothing much, there is a 2-disc version out there, here's a link at my fave dvd-acquiring website, the link will show the items on the 2nd disc.

DVD /CDROM and Hard disks are different media. The way they are designed and how they are made are different. The software which sets up the hardware is the driver. Since the hardware is different the programming model (i.e. list of instructions to setup the hardware ) also is different. \n\nFor example DVD has much more features than a regular hard drive. It has support for error correction which is superior\nThat is the reason the drivers are completely different.

Get a DVD Burner and Nero, and some DVD-Rs Notice that it is a "-" and not a "+"

For standard DVDs, that's it.  \n\nIf you want double layer, you will get DOUBLE.   But this might not work on your television's DVD player. \n\nGood luck and Happy Computing!

DVD-R disks will generally play in older DVD players, if you have a newer player at home, it should play the DVD+R's and the -R's. The -R's are the older format used when DVD burners first came to be. +R's are more recent technology and therefore do not play on the older DVD players. If your burner is new, you may find that DVD+R's burn better in it than the -R's do.

Not all DVD players support dvd+r. Statistically is is a slightly more incompatible format.

There is not much difference, both are writeable CDs. They say that +R is more compatible with most of the computers existing today.
