Ok, just recently got this burner and I'm already experiencing major problems. I've managed to burn nice bunch of regular CDRs with no prob and finally got first blank DVDs few days ago -- DVD-RWs, as all DVD-Rs were sold out. Immediate problems that I need some assistance with: -I stick a DVD-RW in and open Primo and it takes appx. 7 minutes for it to understand that there is DVD-RW inside the drive. -After it has recognized it, trying to erase or burn something to media causes that it looks like its doing something for about 2mins and then returns an error and ejects the DVD-RW. I'm using Datasafe Media DVD-RWs. Pioneer's Aus website suggested to switch from DMA to PIO for my Secondary IDE spot, but it didn't solve anything.
