There's where you went wrong :-)

But besides that, HDTV material is commonly interlaced, but not always
480.  I imagine there are more standards that use something other than
480 (Japan HD, maybe?) but that's all I'm working with.

In any case, I worked out the problems in vf_scale.c and submitted a
working patch to -dev (clearly, no-one but me is interested in it). 
Hopefully it will get accepted, and I won't have to work around this
problem again.
