I’ve trashed 3 double layer DVDRs trying to burn a 7gb iso image using a plextor px-716a burner, which is supposed to be a pretty solid burner. I have never had a problem with a single layer DVDs. I first used Nero 6.6 and now I’m using Nero 7 ultra. I’m burning at 2.4x which is the rated speed of the DVDR (Memorex). Nero won’t let me burn any slower, not that I’d want to. I’ve attached the log. Anybody have any thoughts? Thanks.
