I recorded a program, Atlantis, using a converter box and forgot to use the "zoom" option (some other converters use some other names ,e.g zoom=cut-out).
The broadcast is in analog but the actual movie appears as 16:9 cropped at the top and the bottom.

No what I recorded looks sort of 2/3 of the actual size and I have used Ifoedit to change the aspect ratio but I can't get the same size as the original.
