The problem: Apple movie trailers won't play on your KDE3 Linux web browser (such as Firefox on Kubuntu 8.04). The solution: get the backport of mozilla-mplayer. Of course, you could upgrade to the latest Kubuntu, 8.10, but then you're forced to switch to the KDE 4 desktop, and I'm not going there... yet (maybe in a few more releases).
Figuring out the problem took a little while, viewing the source of a typical trailer page and digging around in the JavaScript. Google searches turned up sub-optimal solutions. The issue turns out to be a browser detection JavaScript that Apple is using, and the fact that the older version of the mozilla-mplayer plugin advertises itself as quicktime "6 / 7" compatible (the script needs to see "7" as the first character).
