Quicktime Changing Frame Sizes and Aspect Ratio

Can someone tell me why, when opening movie files in Quicktime, the frame size and aspect are different than the original file size? For instance, when I open a 720x480 movie it shows up as 853x480, stretching it out as a result. 853x480 is what it says in Movie Properties (under Window in the toolbar).
I have "movie size" set to "actual size" in the prefs. What can I do to get QT to actually DO that?
(This could be problematic because I'm working on a project with an unusual size of 400x192 and I need to make sure it stays that way on delivery)

Try searching QT Player Help on "encoded pixels." Your answer is in properly setting the viewing aperture of the player so that you can see the movie in the form that you need.

Jeremy,
You can't just make up non-standard pixel dimensions in FCP. Unlike Compressor, Motion, and programs such as After Effects and the like, FCP was designed to input and output standardized video formats that adhere to the standards of video dispalys, video tape decks, and video cameras.
The other apps I mentioned are made for outputting to all formats and any pixel dimensions, including those like the web, which have no standards.
So, you need to edit in a standardized format and then use Compressor to output in a non-standard format, otherwise FCP will distort your video in its effort to stretch it to one or another of the video standards it recognizes.

Thanks David.
I have been using Compressor to crop and export, not FCP, with no problems. I was mainly worried about delivering this odd frame size to the client and having them view it in Quicktime with the same stretched result.
