I've spent the price of a new car, keeping my "Nero Burning ROM" updated for the past decade or more, but for sheer simplicity in burning or making ISO's, it's hard to beat "Img-Burn". (and it's FREE)
Folks that offer "Img-Burn" are constantly trying to have the best product out there and updates come at regular intervals.
So I advise anyone using it...... keep it updated.
Oh, by the way, old saying, "a slower burn is a better burn". I learned that years ago from a professional CD maker and I never try to burn any disk at top speed...... 8X is about tops for me.
Cheers mates!
