Hi!

        I know that this is going to be a strange question ;)

        Most of the time folks are interested in deinterlacing a stream
        to create a progressive movie.   I want to go the other way - I have
        a 1280x720 at 60 frames/sec (actually 60000:1001) progressive clip
        that I want to re-encode for a DVD.

        Yes, I know that's throwing away a lot of information but 1280x720
        at "-F 7" (60000:1001) isn't suitable for a DVD.  Scaling to widescreen
        DVD taking into account HDTV's 1:1 SAR is trivial with y4mscaler
        of course.

        The first thought I had was to simply take lines 0, 2, 4, ... 720
        from the first frame and call that field 1, then take the corresponding
        lines (0,2,4,...) from the next frame and call that field 2 and call
        y4m_write_fields() with the two field buffers (and of course set the
        rate code to "-F 4" (30000:1001)).   Is this correct, or should I use 
        lines 1,3, 5 ... from the 2nd frame?   Or will it make much difference?

        Cheers,
        Steven Schultz
