Thanks Darin. A follow-up question: Will the QuickTime plug-ins
developed over Windows work the same for iPhone (other than the fact
that it needs to be ported to using Objective-C)?

The video and audio elements use back ends called media engines,
represented by the MediaPlayer class. At the moment, there are
implementations of media player for the Mac OS X QuickTime QTKit
framework, the GStreamer system for GTK, QuickTime on Windows, Phonon
for Qt, and a media player interface specific to Chromium. Each of these
media systems has its own system for managing codecs.
