Some DVD's are +R and some are -R. What is the purpose? What do they do differently?

    DVD +R has an additional cyclic check to minimize data loss.

    Back when recordable DVD's came out there was two different standards. +R and -R. The first drives only supported one standard. However for several years now nearly all recordable DVD drives support both standards.

    no practical difference as far as you, the user are concerned. you just have to make sure you've got a drive that supports whatever format of disk you've got there
