I am new to DL (Dual Layers) and I am burning Blu Ray BD-REs. Previously with single layer, I would limit the size of a burn to stay away from the edge of the media. This seemed important for junk (Ritek/CMC/etc) DVD+RW/DVD-RWs as the error rate at the end of these discs would go through the roof. The problem is with DL, from my understanding, is that it goes to the end of the disc and starts going backwards. Is there anyway to limit how close it gets to the edge with DL discs. I tried "minimum" on format size and that seemed to help, but the BIS spike at the crossover was still there on one of my DL discs.
