Apple DVD-R Discs

in Genius Bar edited January 2014
I recently burnt a DVD-R but it only appears to have used (physically burnt) half the Disc.

Let me explain...

I had 9gb of video finalised and ready for authoring but it obly amounted to about 40mins of footage so I had to split the film over to discs.

Could someone explain or point me to the exact facts about (Apple) DVD-R discs i.e

How mins of footage it can hold.

I know that 3mins of uncompressed footage is roughly 1gb but do transitions etc make any difference as I can only physically see that one half of the DVD-R disc has been written too!!

I know it's 4.7gb but hey?

Any ideas or specs etc?¿
