There is no real 16:9 "mode" in DV/DVCAM/DVCpro.
DV, et. al. is defined only in 4:3 and computers cannot
recognize when the horizontal has been squashed
amorphically. It takes human intervention to identify
and "decode" the 16:9 picture stuffed into a 4:3 bag.

You didn't indentify which camera was used, but if you know,
you can refer to the URL above and see how various brands
and models cheat 16:9 (they do it differently, some better than
others).
