Thanks, I just figured it out too. Here's what my QuickTimeInstaller.ini looks like:
[QTSETUP]
license_option=0
no_dialogs=true
registration_dialog=false
supress_speed_dialog=true
install_qtjava=false
install_qd3d=true
show_sample=false
show_readme=false
show_programfolder=false
install_qtinfo=true
Also, here's how to customize the settings after the unattended install:
1. Install QuickTime on a test PC, then run it.
2. Set all the preferences however you like.
3. Close QuickTime and save a copy of the file C:\Documents and Settings\All Users\Application Data\QuickTime\QuickTime.qtp. This is where all of the settings are stored.
4. After you do the unattended install on user's computers, replace the default QuickTime.qtp file with the one that you saved.
