I found a way to make it work using the undocumented -nooverlapsub and
expand=xxx:xxx::0 but without cropping or scaling the movie.
If scaling is involved, it fails in both cases. My relevant options are:

-vf crop=704:544:8:16,scale,expand=0:-50:0:0:1 -zoom -xy 640 -nooverlapsub
-spualign 2

Anything I can do to help debug the problem (I'd really enjoy that feature)?
