ELI5:  +R vs -R, when it comes to CDs and DVDs.

I will give you karma.

DVD-R was created by the DVD Forum, the official group behind the DVD standard, in 1997. The hyphen is just a hyphen, not a minus sign, similarly to CD-R.

In 2002, a group of companies led by Sony decided they could do a better job, and so made DVD+R. The main difference is that DVD+R is better at avoiding and correcting errors, both during reading and burning. 

Nowadays most DVD players/burners can handle both, so it doesn't really matter. But if you have to give a disc to someone with an old DVD player, -R will have a better chance of working.
