Currently I've been playing around with Nero Vision with the settings on automatic which always shows a size of 4.37GB out of 4.38GB final size (on the bar at the bottom). I keep reading posts about staying away from the edge of the disk to remove errors but if I change the bitrate (currently at 5074kbits) by even one point (say to 5073kbits) in an effort to chnage the size bar plunges down to approx 3.5GB total size leaving alot of the disk unused. Am I doing anything wrong here?
I do not use Nero much, but there should be an option to set the size of the disc you want. I use 4400MB on Decrypter, but most say to use 4300MB.
