A full list of video / movie input plugins:
There's 3 plugins in that list which support qt/mov, but alas, they also support mpeg and avi, with no way to unassociate them. So, if you install one of the plugins, the default 2.9x video plugin is disabled for MPEG and AVI.
Basically, someone needs to make a strictly QT/MOV-only plugin.
Oh, and yes, the Quicktime engine needs to be installed for the plugins to work.
