Capture oversaturation issue solved...whoops, not solved

    A couple of months ago, leaky capacitors caused me to ditch my epox 8k7a
    motherboard and replace it with an ecs n2u400-a. Before the switch, I was
    using a couple of utilities to control the input from the Philips saa7108e
    chip on my gainward geforce3 videocard (the gain settings are far too high,
    especially on the s-video input, causing some really nasty image
    oversaturation). One of the utilities, called video live wdm (vlio.sys +
    registry entries and a batch file for installation), is a driver that allows
    access to the settings on the 7108 through another utility, called "evip
    manager". Brightness, contrast, anti-aliasing and comb filters, manual
    gain/agc, ntsc (-m and -j), pal, and many other usually inaccessible chip
    features can be adjusted or set; after the motherboard switch, though, I
    have been trying fruitlessly to get the setup to work again. After
    experimenting with seemingly endless versions of nvidia/gainward display and
    vivo drivers, checking motherboard settings, and changing the installation
    and reboot sequence, I had no luck gaining access to the chip registers -
    the evip manager comes up, but the sliders are all at zero and the radio
    buttons are set to the first choices, and trying to move the sliders or
    click the radio buttons is a waste of effort. I have even tried contacting
    the author of the software, Igor Lookin, but as yet (over two months) I have
    not received a response. I am really desperate to get my setup back in
    order, so I was hoping one of you may be able to help me out: I will take
    any and all advice that has a chance of resolving this. Has anyone with a
    similar rig to mine been able to run the video live i/o + evip manager
    successfully? How did you do it? What version of the display/wdm/motherboard
    drivers are you using? At one point, I decided enough was enough and ordered
    a Canopus ADVC-110, but was unimpressed. Aside from an exaggeration of the
    reds (and a slight push of greens), the device squishes the high end of the
    luminance range somewhat, not like my other card, but it is still noticeable
    on some captures containing nuanced whites. In addition, the Canopus DV
    codec leaves behind artifacts that would not be present if I were able to
    capture in Huffyuv with my analog board; so now I'm back to square one.
