Windows Movie Maker format problem

[mariner2]

In Windows Movie Maker, when I publish my movies, they are squashed up to the wrong format, even though they never look like that either in the camera or in the WMM program when I am putting the film together, and they never used to be like that in the past. I've tried different cameras too, so its not the camera.
I make short family films incorporating both still and video, the stills are fine, but the movies are squashed vertically.
I have tried tweaking the 16:9/4:3 ratio settings in WMM, but they still come out too square and not 'letterbox' enough.
Something I'm missing somewhere?

havent used WMM for ages so not sure of its ouput/render settings choices, have you checked all the settings
also
Are you sure its not the software youre playing them back on thats causing the problem, maybe has the wrong settings for playback

I've made dozens of little 3-10 minute films all the same way and they never used to be like this, I can't think what's changed

Problem solved by downloading the latest version of MM. Still don't know what caused the initial problem though.
