There is absolutely no difference between DVD+R and DVD-R. There were different burners in the early days that used just DVD+R and burners that used only DVD-R, but the new burners today burn both formats. Whatever is freely available, you can use the different media. I've used both DVD+R and DVD-R and I haven't seen a difference using either one.
