Agreed that Windows can do it and does a fine job but I have one complaint. It seems that Windows always burns at the max speed the DVD/CD is capable. Does it matter? I don't know but I don't run my car's engine at red-line and I don't burn at the max speed.
I still use an 'ancient' gem of a program for burning ISO files called Micro Burner version 4.
http://jaylach.com/downloads/If you chose to try this utility go to the 'Show' tab and select 'ISO creator/burner'. You would find such features under the 'File' tab then ''Advanced settings'. I'm not saying that this is any better than Windows ISO routines but I DO like to have some control.
It also has the nice feature of being a single file stand alone program that takes no install and can even be ran from a flash drive on any system.
Thanks for the link you gave Steve. I never knew that you could just double click on the ISO file to open the Windows ISO burner. I've always right clicked and selected the option to burn. Hmmm, just tried the double click method and prefer the right click. Still a thanks as I didn't know about the double click.
