i recently bought a usb 2.0 fantom premiere 16x dvd burner, the problem being when i try to burn anything onto a dvd it starts off extremely slow 3x-ish (it will say burning started at 8x) and then about 25% through my buffer will start fluctuating wildly and it’l drop to 0.5-1x. taking 40 minutes-hour to burn a 4 gig dvd. I’m trying to burn from an a64 3200+ gig of 3200 ram and 2 raided 80 gig sata harddrives (raid 0) with usb 2.0 on windows xp. As far as i can tell theres no reason my buffer should be having problems and as i said above even before the buffer goes wonky its burning slow, anyone have any suggestions? i’ve tried burning with nero, sonic and dvd decrypter
EDIT: on a sidenote, i just ran nero drive info and for my internal drives it says autorun on, DMA on but for the usb it just says Autorun. DMA is set to on if available for everything in all my ide channels but the usb drive does not show up under either channel in the device manager like my internals do, do i have to do something special to enable dma on it?
