Is the 115(D) and 116(D) alot better with x16 -R discs than the 111D ?? MCC03RG20 mainly, asking as even though my 111D is serving me well some times it picks up the discs as x4 and the burns although very good at the beginning of the disc there’s always a clump of PIF’s (burnt at x8 and x16) which i didn’t get with x8 discs.
I think 115 is better, 116 is hard to say.
You can use 6X to burn DVD-R.
