Burnproof is a technology that allow the laser to be switched on/off very quickly, so if you have a buffer underrun the drive just stops writing, when data arrives again, it starts off where it stopped without any noticeable gaps. This seems like a natural thing to do, but burners havn't been able to this until now, they needed a fair amount of time to switch on/off which would create non wanted gaps in the recorded data... I have no idea why burner's wasn't created this way to begin with :) -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
