I vote for Nero 5.5. It's incredibly simple and there's no headaches like with EZCD and XP. If you are still getting a lot of coasters, then it's probably something to do with your hardware. My Iomega 12x10x32 with burnproof has only produced one coaster in over 300 discs, and that's because I accidently hit the power cord. My old 2x2x6 burner would produce a coaster 1/2 of the time, even when I left the computer alone while burning.
