> OVERBURNING OUSTSIDE OF A FEW ODDBALL DRIVES WAS NEVER VERY COMMON FOR A NUMBER OF REASONS, WHICH HAD TO DO WITH THE LIMITS OF THE 650 MEG CD'S, WHICH WERE PRETTY MUCH THE ONLY CD MEDIA THERE WAS A NEED TO USE OVERBURNING TO BEGIN WITH.

> WHEN THE 702 MEG CD'S BECAME THE STANDARD, OVERBURNING FADED AWAY FROM THE DRIVE MECHS FOR A GOOD REASON. THE DISKS CREATED USING IT WERE UNSTABLE. ODDS WERE GOOD THAT THE PRETTY MUCH ONLY DRIVE THAT COULD READ AN OVERBURNED CD WAS THE ONE THAT CREATED IT.

> SO USING AN OVERBURNED CD FOR AN ISO DISTRBUTION BASE IS A VERY,VERY BAD IDEA TO BEGIN WITH,SINCE IT'S GOING TO DO NOTHING BUT CREATE UNNECESSARY PROBLEMS IN THE END.
