I'm hoping one of you genius CD freaks can help me out with this --
I am using a Pioneer DVR-109BK flashed with A09 firmware 1.40 in a G4 Power Mac (running Panther 10.3.8). I've made several test burns of a 4.4GB disc image using Roxio Toast Titanium 6.0.9 (the latest version) onto Verbatim 16x media (both -R and +R) and noted some interesting results. At both 12x and 16x speeds, burning the disc image takes approx. 9 minutes to complete. However, at 8x speed the disc image takes approx 6 minutes 50 seconds.
Anyone have an idea why 12x and 16x would take so much longer than 8x? Does this possibly have to do with the different write strategies (8x CLV versus 12x PCAV and 16x CAV) the drive uses?
From what I've read on these forums and the review by CDRLabs, it seems I should be getting burn times of approx. 6 minutes for 16x, and 6m30s for 12x. I can live with the 8x burn speed but I'm mostly just curious to know what is causing this, and if there is a solution. Perhaps different media? Any info or advice is appreciated!
