Pictures are assumed to have sample aspect ratio of 1.0 - IOW, square pixels. 
However, DV has non-square pixels. Therefore, MLT must compensate for the 
differences between each source and the target (project setting). Think about 
this... the non-rectangular PAL DV resolution of 720x576 is still displayed 
as 4:3 even though 720/576 <> 1.33. Therefore, if your project is 4:3, you 
need to supply picture files with 4:3 resolution assuming square pixels.

IOW, resize the image in another tool to 768x576 and try again.
