Comment (by ramitbhalla):

 Now that you bring it up I did it and yes the same issue with mpeg4 codec
 as well. Infact I tried a few more combinations, mpeg4, libxvid and wmv2.
 Then I tried AVI, WMV and MP4 containers.

 Interestingly both AVI and WMV containers have the same issue however if I
 put it into a MP4 container it works fine.

 So the issue is with the AVI and WMV containers not keeping the aspect
 ratio. So that narrows it down (and probably the title needs to be
 corrected). Any idea why?
