QuickTime 7 had become a significant section of OS X as a whole, tying
together new hardware features like CoreImage and CoreVideo for apps
to utilize, as well as critically compositing the Desktop screen. For
the best possible OS X software combination (e.g. optimized for
gaming, or using 3rd party video playback such as VLC et.al. instead
of QuickTime Player), it became weighted that one would test out which
of the QuickTime versions suites you best. Also note, Apple instituted
a major change in CoreVideo behavior from OS X 10.5.5 (& before) going
into 10.5.6 & up.
Leopard OS X 10.5 was built with QuickTime 7.2.1 minimum. All
QuickTime updater package versions allow installation on all Leopard
OS versions 10.5.0 thru 10.5.8 with the possible exception of QT 7.7.0
untested installation requirement (may be only 10.5.8).
The 7.5.5 "Compatibility Update" can be added to QuickTime 7.2.1 thru
7.5.5 and it contains solely a new "H264.component" but Apple claims
this merely "improves iChat compatibility".
