there is no such thing as "storing the frames as interlaced" the way
you "store them as interlaced" is by leaving them alone, not
separating the fields. the yuv4mpeg file might have a header at the
beginning that tells if it's interlaced. if so you can just edit this
in a hex editor once it's finished (the header is plain text iirc) or
patch vo_yuv4mpeg to add an option to specify interlaced.

whatever you're doing, you definitely should _not_ be using any
filters that separate the fields, deinterlace, or otherwise mess with
the interlacing.

ahh, this is exactly what you want, i think.
