Sure thing! Actually, Rebuilder's set for 4.31GB for safety. Certain projects will tend to run over that boundary + or - a few MBs. CCE will sometimes oversize a bit, too. That's probably where you've been seeing a few 4.33GB filesizes from. Jdobbs just wanted a safety net to keep people from having to totally re-encode because of oversizing. You can manually tweak this so that you're using more of the blank disk... but doing so only adds a very marginal amount of bitrate to your project and the difference isn't noticable just by watching it.
HC's becoming more impressive with each release. It's making me wish I'd have saved my money when I decided to buy CCE a few years back. Where where you then, Hank?
