Hello,
I recently got an LG sata 20x DVD-RAM burner (
specs are here) and have gotten 3 for 3 coasters out of it using both nero and alcohol 120%. It hasn't gotten past 8% completion and I've tried lowering the burn speed. I'm using verbatim DVD+R discs so I doubt it's the media. I've left if burning all night and wake up with it still where I last saw it and it will not shut-down without me doing a hard reset. I want to see if I can resolve this before I decide to send it back for a replacement and see if it's just a dud.
