My 4x Lite On LDW-415 is burning my Samsung (rebadged Taiyo Yuden) 4x DVD+R media very slow. Even though I have selected 4x in Nero, it seems to be burning more at around 1x or even less (23% complete at 31 minutes). My Lite On burner is also flashing the red light, instead of the normal constant red light. Anyone know what the problem is? It can't be the media... Perhaps some kind of incompatibility?
