marchitecture to the rescue!
smart marketing people (http://www.everything2.com/?node=marketdroid) like to tell you that something can hold 4.7GB. this is complete BS. it can hold 4,700,000,000 bytes.
now if 1GB = 1,000MB, and 1MB = 1000KB, then all would be well. but it isn't the case. the same for 1GB = 1024MB (2^10), 1MB = 1024KB, and again for bytes
some quicky maths:
4,700,000,000 bytes / 1024 =~ 4589843 KB
4589843 KB / 1024 =~ 4482 MB
4482MB / 1024 =~ 4.377GB.
there's your 4.4GB. minus a few bytes for track lead-ins and lead-outs, disc TOC and the like and you've got your exact amount.
welcome to the world of marketing vs engineering. you're not the first to be bitten by this, and you won't be the last either. :)

I get about 4.2-4.3 gigs on a DVD-R with the Sony DRU500A. (Very close to elvis's math).
