ATI "Theater Mode" => Any other boards out there have the same option ?

    Hi,

    I've read somewhere that the new Radeon board have something called "Theater
    Mode" which enable any "overlay" video to be outputed to the TV-out
    (composite/svideo/component) output of the card while maintaining the proper
    aspect ratio.

    Are there other cards that support that feature ?

    Matrox ? NVidia ? Others ?

    Thanks

    Matrox calls this DVD Max in the G Series boards supporting multidisplays
    (starting with the G450). Probably this is also available in the Parhelion
    and P Series boards.

    In my opinion, the Matrox implementation of this is superior to the
    ATI for the simple reason that you can choose whether the output is
    deinterlaced before display or not. I haven't been able to get an ATI
    to stop deinterlacing before outputing the video.

    Have you bothered to disable flicker removal in the ATI's display
    properties control panel?

    Yes. Well, actually, there isn't a disable button, but a slider,
    from "Min" to "Max", which I've tried reducing to min. I've also
    tried several Radeon tweak utilities, as well as Omega's "Plutonium"
    hacked drivers, where I've tried disabling deinterlace--in both places.

    I think what is happening is there is no way to disable underscan scaling,
    even in "Theater" mode or with overscan support enabled (via tweak utility
    or hacked driver). This is visible by the way the field combing gets
    distorted on an NTSC video monitor (television), and is sort of implied
    by the digital vertical size adjustments in the control panel.

    So.... my media PC does have an ATI card, an ATI All-in-Wonder 9000 Pro,
    because it works fairly well in that application (non-deinterlaced
    output would be nice, but HDTV output is more important to me), but my
    video editing PC uses a Matrox G550.

    The image is underscanned so there is no way to get the interlacing to work
    correctly.
