Re: Losing time when watching videos fullscreen on my old CRT TV.

    Weird. It looks like I isolated down to more. It seems like DVI setup
    and has nothing to do with clone fullscreen video on TV. If I use
    DVI+VGA adapter + VGA cables setup through my old four ports OmniCube
    KVM (from Y2K with its cables), then no time losses. This doesn't make
    any sense to me! :( What is different with DVI and VGA cables and its
    connectors+DVI adapter? Does DVI have something to tell my computer's
    timer or something?

    Also, this is with a 19" Samsung 931BF LCD monitor (1280x1024) with both
    DVI and VGA ports on its back. I even tried unplugging VGA cable,
    switching to another DVI cable, and same problem. Ugh.

    FYI, it is not onboard audio since I disabled it, rebooted (required as
    it told me), and played more fullscreen videos to CRT TV.
