The log looks more or less normal, it kept looking back and forth at the D and E drives for some reason. It reports a successful burn at 4.2X speed aveage. For DL blanks, I would suggest using ImgBurn for better layer break control options. I use the Fab Internal engine for SL blanks. Always select a specific burning speed rather than "Recommended", it will almost always be too fast, leading to read errors near the end (or middle for DL) of the discs.
