As root the entire > burn is at 24x. (burner is 52x, media is 48 or 52x, mostly 52) Hmm - I wonder if that is relevant to my problem? I have burned, occasionally, at 24x, although I generally burn slower. For these ISOs, though, in k3b I tried setting at 12x, 9x and 4x, and every time except the 8x I got a message saying that my drive could not burn at that speed. The speed was then changed to 8x. (I can't remember what the top speed of the drive is for CDs, but I think it's 48x. When configuring k3b I set it to max 24x for safety.)
