Buffer UnderRuN Proof
CD-Writers use a buffer to write cds, the more applications or processing your computer does while burning, the lower the buffer drops. If the buffer gets too low then the CD-Writer doesn't have anything to write to the CD, and you get a buffer underrun error, a coster. that's why people say don't do anything when you're burning, you kill the buffer.
What BURN-proof does is when the buffer hits zero, then it marks the point on the cd where it last wrote. then it waits until the buffer fills up again, and once it does it finds the marked point, and begins writing again as if nothing had ever happened. this makes it practically impossible to coster a cd ever again, and you can do anything while the system is burning because you don't have to worry about the buffer dying. i've tested mine (plextor 12/10/32A) and it just simply rocks anything i've ever seen. burned a 80 min cd in no time at all, the entire time having adobe photoshop, 4 ie windows, outlook express, and quake 3 going all at once. it's beautiful, i couldn't coster it if i tried, short of hitting the POWER button.
