K I'm pretty much a NOOB when it comes to this... I finally got a new computer with a DVD burner... and on the DVD it says that it can burn 4.7GB... but for some reason it won't let me burn beyond 4.2 GB... I'm using Sonic Digital Media Plus v7 and Maxwell DVD-R... usually when I burned CDs with 700, I could go as high as 703 MB... now sure why the DVDs have 500 MB less space oO Unless there's something I don't know...

At first, it might sound a little weird, but funny as it sounds, it's correct: Under a decimal base, a 4.7 GB disc stores 4.7 billion bytes (4,700,000,000 bytes/1000 = 4,700,000 KB/1000 = 4,700 MB/1000 = 4.7 GB), but, actually, capacity is measured using a binary base, so, 4:700,000,000 bytes/1024 = 4,589,844 KB/1024 = 4,482.27 MB/1024 = 4.38 GB, since part of that is used for logical format space and whatnot, you end with roughly 4.2GB of usable space.

Yep it's another way to make you think you're getting more than you really are.
