Why doesnt Quicktime stretch out 16:9 footage so we see it like it should be? It keeps it 4:3.

Some other mediaplayers detect the source as 16:9 and shows it like you would see it on TV!

The only way to show widescreen in Quicktime is to FAKE the resolution like 1024x576 for D1 widescreen/Pal. But this make it much bigger in size and harder to play realtime on some pc's.

Am I missing a function in QT7 to show widescreen like it should be?

You can "fake" the display resolution of an anamorphic QT by selecting the Sizing parameter under Get Properties and manually resizing the image to the desired ratio.

Well try to explain that to customers :)

It should be a basic function. They are at version 7 for christ sake!
No non-squares detection in 2006! This cant be right :)

I agree that it is a bit insane, but if you are delivering to a client, you should probably be compressing to a square PAR any way. If you are compressing to anamorphic MPEG-2, QT will display MPEG-2 at the proper IAR. If you aren't compressing and delivering the source as a file, when the movie is placed in a proper application, like FCP, then it will display at the correct IAR as well.
