Okay, for the first time EVER I'm getting similar grief from a client on this point...

It's always been my understanding that AUTOPLAY did this properly -- i.e. it waited until enough of the video had downloaded that it would never pause again (except where network congestion caused its estimate to be inaccurate).

Are you saying that the AUTOPLAY instead simply tells the plug-in to begin playing the video immediately, regardless of how much has been downloaded (well, after at least one frame has downloaded)? That would be bad, but that's never been my understanding.

Consulting my handy copy of "QuickTime for the Web" (Gulie, 1st ed, ca. QT4, pg. 48-49, 82), the definition of AUTOPLAY makes no mention of any relationship with fast-start, which I think is how I could characterize my (erroneous?) assumption.

"QuickTime 6 for Macintosh & Windows" (Stern/Lettieri, pg 389) makes reference to AUTOPLAY starting playback "when enough data has been sent". This IS consistent with my long-time understanding of how AUTOPLAY works.
Which is it, folks?

The "autoplay" attribute tells the plug-in to begin playback as soon as enough data has been downloaded for the movie to play through without pausing for more data. It estimates the time based on the rate at which the movie is downloading vs the movie's data rate. Usually it is fairly accurate, sometimes it gets it wrong.
