Confused about DVDs...

[Rip the Jacker]

Well I was watchin the Michael Meyers A+ Cert training videos and came to the CD/DVD section. He went through the different DVD versions...

I wrote down these straight from the audio as notes...

The most common DVD is called DVD-5 or Single-sided. This is 4.37 GB / 2 hours of video.
DVD-9 is dual layered, and single sided. You get around 7.95 GB / 4 hours of video.
DVD-10 is double-sided and single layer. This is the 2nd most popular type of DVD. You get about 8.74 GB / 4.5 hours of video.
DVD-18 is dual layered and double-sided. This gives about 16 GB of data or 8 hours of video.

I'm a little confused. Where is the 4.7 GB DVD in all of this? Is it supposed to be DVD-5 ?

4.37GB is actually 4.377 Gibibytes (GiB) - binary gigabytes, where a "gigabyte" is 1,073,741,824 bytes.
New standardized gigabyte rightfully follows the kilo, mega, and giga prefixes that everyone knows and loves. A DVD is 4.7GB - 4,700,000,000 bytes. That would be the same thing as the DVD-5 that you mentioned.

Any double-sided DVD is the most hated! They hardly ever make them anymore. They're sometimes called "flippers"

A oweneda couple (Directors cut on one and studio cut on the other), but would greatly prefer them being on seperate disks
