Hmm, are you sure about that? I just tried counting frames with nextTimeStep and getNextInterestingTime still shows nothing for an MPEG track, ie. it steps straight from the beginning to the end of the track. That's using the Track version. If I use the Movie version of getNextInterestingTime it steps through one time unit at a time, reporting that my 15 second MPEG movie has 9000 frames...

That's very odd. I don't usually work with MPEG tracks, so I can't honestly say that I've ever single-stepped through a real live MPEG track. I found out about nextTimeStep straight from <http://developer.apple.com/qa/qtmtb/qtmtb54.html> and <http://developer.apple.com/techpubs/quicktime/qtdevdocs/REF/refMovieToolbox.29.htm>. Those pages look pretty unambiguous; if nextTimeStep really doesn't work, then that would definitely be a bug worth filing.
