        I couldn't remember either ;)

        Ok - thanks.

        No, I do not believe it does.   But since libdv needs to be
        installed first (so that mjpegtools' ./configure can detect
        libdv) I always do libdv first.

        A couple things come to mind.   One is important for NTSC
        folks (and less so I imagine for PAL) and the other for
        anyone using Kino.

        For NTSC users the DV data is in 4:1:1 format and smil*
        can be built "--with-avcodec" to use ffmpeg's libavcodec
        for DV decoding.  It seems to give better results and is
        ~10% faster than libdv.

        The other benefit is that smil* can use Kino .smil files.   Using
        something like "smil2yuv -c N ..." it's possible to extract for
        encoding only specific scenes/chapters from a Kino editing 
        session.   I've found that capability very useful.

        Cheers,
        Steven Schultz
