Hey,
I don't know what am I doing wrong, or how is this possible, but I took time how long it took to erase my 2x 4.7GB DVD-RW disc and write the latest testing Dual Core iso of Archlinux with both ImgBurn and Windows' own Disc Burner and found out that ImgBurn did this in 8:18 (mins:secs), while Windows' own decided to take only 6:46.
I even re-wrote(/erased) the disc two times with both burners - results were still the same. No anti-viruses, no old firmwares, no nothing. My system is a up-to-date Win 7 (SP1) with the latest version of ImgBurn (2.5.6.0).
How is this even possible?
