> Burning at a slower speed usually does NOT increase burn quality. You may have a bad writer or bad DVD R's. Use DVD-R's for maximum compatibility.
not quite. with modern high speed DVD burners, like 16X and such,
burns faster than 8X are burned in a CAV mode (constant angular
velocity) where the data transfer rate speeds up as it gets farther
along on the disk. I've found the read error rate is significantly
higher towards the end (outer tracks) of full DVDs burned this way, but
disks burned at 8X are CLV (constant linear velocity), where the RPM
drops as its burning to maintain a constant data rate, and on disks
burned this way, I get far fewer read errors.
