There's no download on the Apple site for Tiger users because Tiger comes with QuickTime 7 and they presume you won't go deleting things you want. You hardly expect a seperate download for Mail in case you trash it do you?
Assuming you just deleted the QuickTime Player application (not the rest of QuickTime which lives in
/System/Library/Frameworks/QuickTime.framework - DON'T TOUCH the framework) using
Pacifist to extract the QuickTime Player application is the easiest way for you.
The only other method is to do a reinstall to restore it.
