The theory I've heard is that it's actually an MPEG-2 licensing issue; instead of licensing per copy of iDVD sold or distributed on a computer (which gets especially costly with upgrades), they license per DVD-R drive sold, since iDVD won't write to anything else. At a royalty of $4 a pop before 2002 and $2.50 since, that could add up to some pretty serious dinero. And, unlike the MPEG-4 licensing fees where there's an annual cap, I don't believe MPEG-2 producers have this safety net. For MPEG-4 encoding and decoding, Apple pays a flat $2 million per year; they hit the cap (25 cents per encoder, 25 cents per decoder) in well under a month just from the free QuickTime downloads online.
