Look around on the net for fast-start enabled aac. That’s what you need — metadata at the head of the file, not the tail. iTunes can play that.

Running the MOV file through qt-faststart and send that (i.e. without going through ffmpeg) doesn’t seem to help. iTunes still hangs up.

Could we please revisit this – it doesn’t compute…

I’ve converted my AVI to MP4, ran it through MP4Box (http://castfortwo.blogspot.com/2007/10/make-mp4-files-faststart-with-mp4box.html) to make it faststart… Streaming that file still makes iTunes to hangup…

And the -hint option didn’t help either…
I read somewhere that the version of iTunes matters – mine is 7.5 (19)
