Not so much a problem, but perhaps a better moment.
I’ve noticed that on different brands of media (inc. RiDisc, Bulkpaq, Greenpod, etc etc… All mediocre brands) I usually burn them at max speed, and after one of my Datawrites borked whilst verifying on IMGBurn, (because of the max speed) I’m lowering the speed to play it safe. (However, usually a max speed on DVDs too - NEVER exceeding 12x)
Fair game, but can varying burning speeds affect readability, consistency, etc? I’m going to be borked if my data goes in three months because I burned it too fast :o
