while I'm here, is it normal to be able to burn a 4.5GB DVD-R at 8x in just over 8min.?? I was expecting it to take alot longer!
That's about right. It does tell use that your system is performing OK, DMA set right etc.
It is most likely that the CD speed issue is down to the media not being liked by the burner.
I use Verbatim CD's (Pastel, Super AZO & Datalife Extra Protection) & some Sony. All burner at max speed.
Used to buy whatever was cheapest , both CD & DVD. Not now though, I go for quality.
