Apple 4.7 GB DVD-R's

How come the Apple DVD-R discs say 4.7GB on them, but they are only 4.29GB in reality? Are other brands closer to 4.7GB in reality or are they all 4.29GB?

Unformatted drives/disks are always larger than formatted ones. I hadn't noticed on the DVD-Rs but the "missing" amount looks about right for formatting loss.

This isn't special to Apple--look a your hard drive and see how big it is. A 20GB will format to around 18. The bigger the drive, the bigger the difference. They always advertise the unformatted size. It's normal.

its got to do with formatted block sizes as i remember

All DVD-R's you only get about 4.3-4.4GB usable space, don't worry about it. And don't waste your money on expensive Apple branded DVD-R's either! ;)
