Who else overburns data or audio CDs so they hold more than their actual amount? How many minutes can you squeeze in over the 80min limit? What's the best 80min 700meg CD brand for overburning? The most I have ever overburnt by was about 3 and a half minutes on top of the initial 80 minutes. I do this a lot but the brand of the CD depends on the amount you can overburn by.
