I have few cake packages of old Esperanza DVD+R 4x media (Mnf ID: AML 001). They were cheap but good enough when burned as 2.4x on my old Asus 1604 drive.
Now appeared I can burn them at 4x speed only. Anyone tell me please how can I set lower than 4x speed on my Plextor 716A? I've tried already to disable PowerRec (making no difference), enabling VariRec (it have 4x only speed option for this media), playing with Nero recording options -- all those things failed
Also, is 716A sensitive to vibration? I have 4 big coolers inside case, 3 harddrives, watercooling and all that stuff making case to vibrate a bit.
ps. I'm using Nero Express 220.127.116.11a for burning disks. Previously used 6.1 but that made no difference at all -- only bitsetting option appeared in 6.6
