I'm using a Samsung SH-202N to burn these discs, and i'm only reaching 16x?
They're from a 50-pack from BB (on sale this week) which by all counts, have been recommended more highly than 100-packs, and they refuse to burn faster than 16x, regardless of how full they are (most are image files sized specifically for DVD's, so they're 4,675,000,000 bytes.
I had a 100 pack before, and they hit 20x without fail.
I would say 1/5 of these discs hit 20x, but the other 4/5 only reach 16x.
I realize this isn't a huge ordeal, as Sony discs are often restricted to 4x, but i've never had a problem with verbatim discs being restricted to 16x. And i have over 700GB of images i need to clear off my computer, which is why i spent the extra coin on verbatims (expecting to reach 20x)
Some extra information:
-Vista x64 ultimate
-256MB read buffer
-SH-202N (on it's own IDE channel)
-average write rate only reaching 10.5x!!! (Clocks in at 5:00~5:30, and i want to be at 4:20)
Any ideas? Like i said, 1/5 still reach 20x, so it's being restricted by the firmware, possible write errors/media imperfections?
