The + and - do mean some thing. Just the same as CD + / -.
Google son! :P
Single layer DVD's:
DVD- slightly, and I mean slightly holds more data than a DVD+ disk.
For double layer:
DVD+ holds slighty more data than a DVD- disk.

DVD+ is more stable and recently developed than DVD-.
With older DVD drives, like 1997 to 2004 you only had DVD -.
DVD+ Drives showed up around 2005.
And currently made DVD drives usually support both formats. Check the package on the drive and it will tell you what it supports. Or check the manufacturer's web page and you should be able to find out that way. :P

And yes....I am leaving out DVD+/-RW's :PPPPPPPPPPPP

Nice.... No +rep or likes.....good to know and keep in mind in the future.

Sadly.....WIKI had some good insight...... :( :P

I think it means the plus and minus of the bits on the dist you know the 0 and 1 that make up all the data 'info' at least that's my theory at the moment.

Did look it up on google and didn't say much about it really.

For computers....
"0" and "1"....Off and on. Either one makes up a bit, just depends on what result you need for-> A series of 8 bits, make up a byte. Check up on "binary", "bit" and "byte" to help you fix your point of confusion.

PS. Google "DVD-R", "DVD-RW", "DVD+R" or "DVD+RW" and look at the Wiki pages that come up.
While in Wiki. Click on the links about the other standards. DVD-R/DVD-RW and DVD+R/DVD+RW. They will lead to graphs giving you the info you are looking for.

How about....
