they can be pressed but i dont recomend it, they wont play in every syetem, the most you can go is about 78 min, your on your own if they dont play right,i dont know any plant thats gonna tell you they will cover the cost if they dont play right, the equipment is not made to go over 74 min but they can squeez a few more mins onto the disc surface but not 79-or 80, trust me on this ive pressed over 700 thousand cds in the last two years
