Burn speed issue

[sspeelmans]

I bought a spindle of 10 verbatmins 8x dvd+r dl. ImgBurn wont burn them them at 2.4x, only 4x-8x. My dvd drive is a sony dru-830a and its compatible with the speed 2.4x. Is it the discs i bought or what? Also wont burn at 2.4x with cd copy.

That's the slowest speed your burner/firmware/media combination allows, besides, burning 8x rated media at 2.4x doesn't usually result in good burn quality.
