Unable to export Uncompressed 10-bit 4:2:2 in 16x9

Hi guys,

I feel pretty dumb asking this, but... how come every time I try to export an Uncompressed 10-bit 4:2:2 Quicktime from AE, the rendered video comes out squished to a 4x3 from a 16x9, as it is set up in the Composition?

Here's what I do. I set up a render via Render Que. Specify Uncompressed 10-bit 4:2:2 as encoding. I tried a few different options from the "Stretch" variables: locking aspect ratio to 3:2 and unlocking it; specifying the stretch variable to DV NTSC Widescreen and leaving it grayed out as default... same result. The render squishes the movie to a 4x3.

I thought that, maybe, it's just my Quicktime player that misrepresents the image... but that's not the case, either. I tested the rendered file in a new Comp in AE -- it really is squished. Also, I rendered a DV/NTSC-encoded movie of the same sequence for reference, specifying that it should be a 16x9 move, and that came out 16x9, as it should, and it played as such in Quicktime player.

So... would anyone happen to know, what is it that I'm missing?
