    While watching a video in a Windows 7 virtual machine run through Parallels, I need to prevent the system from dimming the screen / going into sleep.

    I was suggested installing "Caffeine" http://lightheadsw.com/caffeine/

    If I install this little program in my Mac, and use it, will it override any dim/sleep mechanisms from Windows 7?

    Thanks!

    Yes, if you're running Windows in a VM at the time.

    The Windows 7 virtual machine is a BootCamp partition linked to Parallels, but that shouldn't be an issue / relevant to my purpose of preventing the screen from dimming/going to sleep, right?

    If so, I'll just go ahead and install Caffeine...

    Correct. OS X is your primary running OS when running Windows in a VM - linked to a BootCamp partition or not. Whatever you set OS X to do with the screen, is what it will do.

    And this has nothing to do with Parallels Tools either, I suppose?

    The Windows 7 virtual machine can still dim its own display unless you disable those functions within Windows. If you're running it in a virtual machine through Parallels or VMWare, I can't see any reason to leave any of the energy saving settings enabled in Windows.
