The dvd size after i put my dvd through rebuilder is 4.23g's and i was wondering if you can alter the output size to make it bigger.
To my knowledge I don't know of a way to set the size. I've read of others having their finished goods come in a bit undersized with a the newer versions of RB.
If you look in my advanced guide you'll see the setting for size. It really shouldn't make a noticeable difference since you're already using almost 96% of the disc at 4.23GB but you can change it.
