Size Problem With Movies In DVD5

Hello friends!

I want to burn a few movies in a DVD5 4.7 GB , but every time I try to add videos to it, I am allowed to add only 4464 MB. If we calculate 4.7 GB, it turns out to be 4812 MB. So why are we not allowed to use all the disk space to write the video files. Where are the rest 348 MB alloted to.

Thank you.

The 4.7 GB capacity claimed on DVD packaging means 4.7 * 1000 * 1000 * 1000 bytes, which is the same as 4.38 * 1024 * 1024 * 1024 bytes a.k.a. 4.38 GB (GiB), or 4482 * 1024 * 1024 bytes a.k.a. 4482 MB (MiB).

In other words your main problem comes from the slightly different ways of interpreting exacty what a “Giga” or “Mega” byte is.

The 4464 MB limit instead of 4482 MB is probably just for the necessary overhead in your authoring or burning program.
