HD and DVD manufacurers use base 10, not base 2.

Yes. And there are no SI standards for data, therefore, they should be using the de facto standard for computer data, Base Two.

[livejournal.com profile] faboo insists that ANSI and ISO have defined those units to be with relation to the base-2

I've heard of IEEE coming up with the Ki, Mi, Gi, &c. to ensure base-2-ness, but it doesn't really solve the problem that a gig of ram is 1024 groups of 1024 groups of 1024 octets of bits, and a gig of hard drive is 1000 groups of 1000 groups of 1000 octets of bits.

I also felt cheated because when I buy CD-Rs they say 700 MB on them and they have 700 MiB on them.

I just bought a stack of DVD+Rs and they said 4.7 GB, but they only have 4.4 GiB — 6% less than advertized.
