I have found that under certain circumstances, specifically when the input geometry (x and y values, i.e. 720x480) and the output geometry are identical, certain letterboxing/zooming options fail inexplicably. In some cases I have bitten the bullet and re-encoded the source to something slightly different (like 704x400 for 16:9 content) and then transcoded to dvd from that. Does that sound like the same issue?
