Hi all experts!

I recently bought myself a Samsung SH-W162L (Lightscribe) DVD-writer and I have some serious problems with it. I can not use it in DMA mode. Windows locks up completely when I start up my burning software (Nero or DVD-Decrypter). It does work fine when using it in PIO mode, burning at ~1.5x but this is pretty painful.

I have it installed as master (jumped as master) on my secondary IDE channel. I use an 80-pin cable. I have the latest firmware. I have DMA enabled in my BIOS. I have DMA enabled in Windows XP SP2. I tried to force the DMA through the registry. I tested it in a fresh Windows XP SP2 installation. Same result. Actually I have followed every recommendation but it won't work. (I tested it in my girlies Compaq but that computer has no BIOS so it always shows up as PIO, weird.)

So my last hope is to you guys before it goes out the front window (not XP this time).

Thanks!

My system:
ASUS P4C800 MB with Intel 875P chipset
Pentium 4 2.8GHz, 768MB RAM
Seagate harddrives, 80G on primary and two 250G's on external IDE controller (tested both with and without this controller)

Thanks for all the help guys!
