I created a disk image .iso using DeVeDe on a linux machine. Now I'm trying to burn that image to a dvd on my Mac computer using "Disk Utility".
The .iso is 4.4GB, using a DVD-R that holds 4.7GB. It's saying the DVD isn't large enough to burn the file.
According to my calculations, there are 0.3GB more space than I need on the DVD!
Why is it saying the DVD doesn't have enough space to burn the file?
You are ignoring "head room" that DVDs need for titles, indexing, etc. The finalizing process also adds to the space. If you don't leave 5% or so you are looking at burning a coaster.
However, there are some burners, such as Toast, that can compress the file sufficiently to fit on a single DVD. I have written 6 GB movie files to a single DVD. Naturally the quality suffers but if it's an old movie or one DLs from the net, it's moot.
This only applies to movies etc., never to a data DVD which has to be copied perfectly, bit for bit.
