I bought a brand new 4570 yesterday and immediately flashed to 1.Z1 FW.
My PC identifies 4570 as DVD-RAM when the drive is empty(with no disc inside the drive).But when blank DVD-R (Verbatim Mitshubishi Comp. 16X) is inserted in,my PC is identifying that DVD-R as CD-ROM.
Also others DVD R+(SONY) and DVD-R(Fuji Film) media burned in Samsung TS H552 when are inserted in 4570 my PC is recognizing them as CD-ROMs and my system (XP) slightly freezes up while i am trying to start up reading of the inserted disc.
I am able to burn the DVDs even PC says it is not DVD.But I can read that burned disc untill first eject only.After that when the burned disc is inserted again the drive works slowly and says that it is a CD-ROM not DVD and system slightly freezes up.
Thats all nothing more.But it could be enough i guess.
So as a newbie of this branch i am saying that any advise will be very pretty appreciated!!!
…aaand CD-ROMs work good for me just those DVDs not.
