It may be time for an RMA. The 6X disc just coastered. I hate Plextor!! It is ridiculous to make the consumer beta test their drives. In short, to be sure you have a good drive, you must test it with every type of media known to man (DVD-R, DVD+R, DVD+R DL, not released DVD-R DL, DVD+RW, DVD-RW, CD-R, and CD-RW), and then, if you get good results on all types of media (using high quality media of course), you may have a good drive. I am not doing that again! This is not my first rotten experience with Plextor--Plextor screwed me with the 48/24/48A. If I get an RMA of my 716SA, it will not be a refurbished drive, but a new one. I know what Plextor USA's policy is, but I will threaten them with Better Business Bureau involvement if they do not do what I want!
