Can somebody please explain how a
4.7 GB DVD-R turns into 4.28 GB when ready to burn?

Volume information. If you use, I believe, Disk Utility or Toast I believe you can get more (4.4 with Toast). Same way my 60GB harddrive is only 55.6GB in capacity.

Probably also something to do with the way "megabyte" and "gigabyte" are defined.

4.7GB assumes 1000^3 and 4.3GB assumes 1024^3, is my guess.
