What is the true size of a "4.7" GB DVD-R?

[Super Warrior]

I know its not really 4.7 GB,cause they look at it differently than Pc GBs or something.So what is it really? I think i heard it was really 4.34 GB.

The size is supposed to be
4.700.000.000 bytes =
4.700.000.000/1024 = 4589843.75 kB =
4.700.000.000/1024/1024 = 4482.27 MB =
4.700.000.000/1024/1024/1024 = 4.38 GB

Give and take a few and you come down to the fact that what you have heard is true. In contrary to CD-R(W) the manufacturers of blank DVD-discs has decided to follow the same path as the hard-disc industry and state the empty space in SI-units instead of "computer-units".

Keep your total files' size to 4.37 or less (e.g., DVD2ONE usually comes up with 4.36 GB) and you should have no problems with burns.

true if you are using quality media. Some of my Princo have visible surface defects on the last outer 1/4 inch. I keep those for 1.5 hour movies only. The perfect Princo's do burn 4.37 properly. Now I know why Princo Bulk is "B" Grade. Just ordered 100 printable Ritek from rima.com.
It will be nice not to have to inspect disc surfaces with a magnifying glass before each burn. geesh Live and learn
