Dan,
QuickTime Player is not color-managed (at least not in the Mac OS up to 10.5.x, as far as I know, since I'm not yet using 10.6.x) -- which means that what you see on the screen is shown using the currently active monitor profile.
So, the task is really very simple: open the movie in QuickTime Player, stop it at the frame that you wish to make a still of, take a screenshot (Command-Shift-4, then select the area to copy), open the captured screenshot in Photoshop and make sure that it has been assigned the active monitor profile. If it should not open as having an embedded profile at all, or if the embedded profile should be different from the active monitor profile, then assign the latter to the image (important: ASSIGN, do NOT convert!), and it will match what you see in QuickTime.
If you need to publish the image on a web site, for example, then you should CONVERT it from the monitor profile to sRGB (which is often enough the preferred compromise on the web), after which you optimize its size and format for online viewing.
