In follow up to my own post on the failure of old movies exported using the
'Apple Animation' codec:

The defect is in Apple's new versions of Quicktime. Both Quicktime 7.3 and
7.4 fail to play these movies. After reinstalling my entire OS, with
Quicktime 7.1.3 and OSX version 10.4.11, all of these movies now play
perfectly. I've not tested Quicktime 7.2.

As to a solution... I've heard nothing at all from Apple. I'm not going to
upgrade Quicktime again for at least a year. My advice is to be very wary up
performing any Quicktime upgrades before a presentation! The new versions
(7.3 and 7.4 for the Mac) appear to have _many_ bugs, judging from the
online discussions.

Every other Mac-based player I tried failed in exactly the same way, despite
many good suggestions from the list. Ultimately, I will need a Mac fix for
Quicktime, or else I will have to re-export thousands of movies...

     -Thanks for all your advice.
