DVD shrink - size question

[denz_ngr]

How come when I rip a DVD to my HDD using dvd shrink the maximum size of the file/s it will create is 4.35GB? because a blank dvd is 4.7GB right. Is it because it needs extra room for something???

thanks

The maximum I get using DVD Shrink is 4.464 Gig, this fills a 4.7 Gig DVD blank, manufacturers state this size as it sounds better.

Techies please explain in detail!.

By the way DVD Shrink is the smartest piece of software I have every used,
and it's FREE!.

well that's strange.. the max dvd shrink makes for me is 4.35GB...

that couple extra hundred MB would sure come in handy sometimes!

It has to do with the definition of a MB. There are two different ways the term is used:

1MB = 1,000,000 bytes
1MB = 1024x1024 = 1,048,576 bytes

Or

1GB = 1,000,000,000 bytes
1GB = 1024^3 = 1,073,741,824 bytes

We companies sell HDs and media their marketing departements like to use the 1GB = 1,000,000,000 bytes defintion. But the your computer uses the 1024^3 defition. That's also why formated HDs are smaller than advertized.

4.7GB / 1.073741824 = 4.377GB

So you can get 4.3GB of computer data per DVD. It's all marketing BS. Another point of confusion is that some programs use different methods to report the size of a file. I've burnt 4650MB files to DVD (actually size on HD is 4330GB) so you have to watch it when encoding and authoring or you could run over if you're trying to completely fill a blank disc.

yeah how about this, when I use dvdshrink SOMETIMES, when I compress it down to fit on a dvd-r 4.7 when it goes to compress it says that the size is small enuff to fit on a dvd, i think its 4464 mb, but whatever, the status bar is green it will back it up on my HD, but when i go to burn it, copytodvd says its too big, like 4.41. SO when i check it threw windows, it tells me also that the folder is 4.41!!!
