I just finished my 100th burn on these discs; not a single coaster! Some people have reported trouble with the discs, most likely due to their hardware.They are a little slow, but not too bad (about 15 minutes/dvd for my system).I'm using Nero 6 and an HP dvd 530i. So far, the discs have played in every home DVD unit that we've tried, as long as they can read CD-R/MP3's.
