I believe the needed file from Quicktime version 4.0 (and probably 4.12 also) is "QuickTime.qts" which is mentioned by "Dave Darkarts" in this thread on the GameFAQs website. But we just installed QuickTime 4.0, rather than try to do what he described, i.e. "extracting" that file from the QuickTime installation. If that file could be obtained and added to a more current version of QT, possibly the advantages of the newer versions could be enjoyed... or maybe not!
Thanks for your help!
(P.S. I am still receiving no e-mail notification of replies to this thread; all my settings are correct for that option.)
