Aspect ratio

[Digiface]

I have couple files, that when i open the file, AR is not (or does not seem to be) right. With one file, if i change video renderer from default to WMR7, AR is correct, when i open the file.

I also got one file, that i'm not sure which AR is correct. Other AR doesn't look too streched and other not too shrinked. I mean with default renderer picture is bigger (more streched) and with WMR7 smaller. I can't for sure say which one is correct.

How can i be sure that right AR is always displayed?

Does this look correct AR? (I can't take a screenshot with WMR7 renderer.)
