    Ok, Just got a BFG GeForce 7800 gsoc. Has a Nvidia 7800 chip. 256
    memory. Fully supported for Premiere 2. Problem is that the computer
    monitor is very jerky when NTSC monitor is running. About 1 frame a
    second. NTSC monitor is fine. When NTSC monitor is off, computer video
    playback is fine. My old Matrox 550 would pull both monitors fine.

    I am running Premiere 6 presently. Hope to upgrade to Premiere Pro 2
    in the next few weeks .

    Have 2.4 Intel processor, Asus P4C800 deluxe MB, 2 gigs rams. Dual
    computer monitors.

    Ideas? Iam concerned new video card might be damaged. The packaging
    was ripped as if from a blow.

    Sounds normal to me. The older version concentrated
    resources on keeping the output DV stream in real-time
    and only updated the computer-screen "monitor" ~1FPS.
    The newer versions take advantage of faster processor
    resources and can keep both updated in real-time.
    Not to worry, IMHO.

    I don't understand. The Matrox 550 with 32 meg would play the timeline
    on NTSC and computer monitors. The Nvidia with 256 meg won't.

    To make things more confusing. the Matrox would not play capture
    footage on both computer and NTSC monitor.

    Sounds like a driver capability and/or compatibility issue.
    As long as it is actually capturing/editing/outputting properly,
    this doesn't seem like a show-stopper problem. There are
    several years difference between the release of Premiere 6.0
    and the development of your video card (and drivers).
    Lots of those things are configuration-specific. Premiere
    seems to behave differently with different resources.
    It seems like an annoyance to me that would be remedied
    by using a less-ancient version. Might even be resolved by
    re-installing Premiere (now that you have a new video
    system), but I wouldn't risk it myself. Not broken enough
    to take that risk.

    Pretty much a pain in butt to not be able to edit using Premiere's
    monitor. Awkward.

    Doesn't the monitor return to "normal" if you turn off
    or disconnect the Firewire device? That is how it works
    on all the machines I have tried it on.

    I wanted the ability to edit and check it out on the NTSC monitor. at
    the same time. Used to be able to do it on the Matrox 550. The new
    card a GEForce 7800 has 236meg of memory. Would not do it.

    Downloaded a trial copy of Premiere Pro 2 and both monitors are
    finee...the marvels of computers.
