DVD creation footnote: a pet peeve

Here's a minor annoyance that didn't affect the DVD creation process but still merits a mention. If you look at the 'Status' of the DVD being created, the maximum DVD capacity will show up as 8.0GB for double-layer project and 4.0GB for single-layer project.



The unit 'GB' is calculated under 'kilo is 1000', which is used by the storage device manufacturers, not 'kilo is 1024', which the operating system generally uses. Now, the unit itself isn't really a problem since as long as I know exactly how much I'll be using, I'm fine with that. The annoyance arises from the fact that under this unit, a double-layer DVD holds 8.5GB and a single-layer DVD holes 4.7GB. This means that iDVD does not let me choose to add 500 or 700MB worth of more video onto the disc even though the space is available. That's a sad waste of space. The extra space could have been used to either put more footage, or if 4-hour (or 2-hour for single-layer) limit must be kept, used to increase bitrate and thus quality of video.
