first excuse my english, IÂ´ll try my best.
Okay, here we go:
I own a Benq 1620, flashed to the "Pro"-Version and upgraded to the latest B79T-Firmware.
After that, I burned a few "Platinum" (RicohJPN02 8x) with 16x speed, burn time was approx ~6 to 6:30.
All of a sudden, the Benq didnÂ´t want to burm then 16x anymore, although the burning program (I use CloneDVD mostly to burn movies) showed 16x.
Burn time then was approx 10-11 minutes.
So I tried a little voodoo with the "flash safe to B7L9, burn a disc, flash safe to B7P or B7T again", the first burn with B7L was a winner: ~6 minutes. Flashed safe to the B7T again, no luck, burn time increased again to approx 10-11 minutes, flashed the B7P - no chance.
So IÂ´m sitting here with a bunch of discs that once could be burned with 16x, now just 8x.
Checked the cables, DMA, everything.
btw: system specs are Win XP Pro SP2, Sempron3100+, 1Gig Ram, 2x 7200rpm-harddisks, all the latest drivers (SiS-Chipset that is), burning with CloneDVD 18.104.22.168, before that 22.214.171.124.
AnyDVD is running in the background (126.96.36.199).
