First sorry the date's wrong should be
2011-01-11 and I think I got it on a Myst forum with problems like this with Rhem BUT dealing with Riven and MystMasterpiece. At the moment I have not been able to find the site but I'm searchin. I do not know if The later Quicktime program works with Rhem 2 but I do not think so. Except for the new release in 2010 Trilogy(Rhem 1-3) for Lace Mamba wich uses QT 7.

There is also a good chance to get it to work, installing the QT on Rhem 2 and as I mentioned copy the .qts file in the Rhem folder.
