how to get best dvd video quality at 3Mbps?

    I need to cramp about 3.5 hours of video onto a dvd5, so the max video bit
    rate I can use is around 3Mbps.

    I tried tmpgenc and main concept, both produced acceptable result but when
    there is fast motion, I see blocks.
    Strangely, if I encode at 6Mbps, I still see blocks with tmpgenc but
    main-concept is smooth.

    Both are run using 2 pass vbr at highest quality. I thought the idea of
    2-pass vbr is to distribute bandwidth where needed. That means tmpgenc
    should allocate some bandwidth away from the non-action portion to the
    action portion, which means I should see blocks everywhere, not just where
    there is fast motion, right?

    If I use main-concept to encode the video at 6Mbps, then output the dvd to a
    folder and then run DVDShrink on the folder, would the result look better
    than if I encode everything at 3Mbps?

    you can try YASA DVD to iPod Converter,it has professional video/audio
    code setting,

  3. The most obvious question to me is - does the video actually have to
    be played on a stand alone DVD player ? If you can playback on a
    computer, you can do an awful lot of good at well under 3mbps ;-)

    That'd make for very nice MPEG4, WMV or H264 video with good quality
    audio streams. MPEG2 isn't that great at retaining image quality and
    introduces motion artefacts compressing down to the levels you're
    talking about.

    Cheers - Neil
