        Ah, so it sounds like you have the mjpegtools package installed.  Do
        you have the latest release (1.6.0)?

        Broadcast TV (at least in the US) is terribly noisy which doesn't help
        mpeg compression.   Then VHS is a low quality medium which further
        degrades the signal.   Getting watchable movies from that combination
        is difficult.

        Have you tried the yuvdenoise program that comes with mjpegtools?  It
        did absolute wonders for the 40 or 50 VHS tapes I encoded to SVCD/VCD.
        Oh, I also found out that VHS tapes do not age well (some were 15 years
        old or more) - to correct the contrast/color/etc I bought a Sima SCC
        (color corrector) unit which worked very well (cheap too - $100 as I
        recall).   Between the Sima unit and the yuvdenoise program I obtained
        watchable (they'll never be "great" of course since the sources were so
        poor) VCDs

        That's what I did to one cabinet of tapes - got a couple more to do 
        eventually.   The laser discs I will do last, it'd be nice to save 
        those as DVDs but I haven't found any DVD software that doesn't require
        windoze.

        Cheers,
