I 12:23:04 Average Write Rate: 0 KB/s (0.0x) - Maximum Write Rate: 0 KB/s (0.0x)
I tried with a different write speed (10x set via Tools / Automatic Write Speed) and it worked, but I got the error "W 12:31:45 Write Speed Miscompare! - Wanted: 1,764 KB/s (10x), Got: 8,468 KB/s (48x)" in the log
I then noticed "(Speeds: 8x, 16x, 24x, 32x)" in the log, so I tried setting speed to 32x, and it failed again.
The CD-R has 52x written on it -- how do I know the maximum speed to set for a CD-R (I'd assumed that choosing "MAX" would cause ImgBurn to select the maximum speed for the loaded media)
