Hello, Windows 7 contains integrated isoburn.exe program, but when I need to write iso file in Windows 7 I want to ask what you all others prefer integrated isoburn.exe or other programs. What you use? On which speed isoburn.exe is writing CD-RW 700Mb 8x-12x media and DVD+R 16x 4.7Gb media? What you are preferring and recommending for others who is using Windows 7 or Windows 8? One problem is that using isoburn.exe you cannot set writing speed. Question is because my hobby is science and I am IT tester, enthusiast. Thanks.
