I was playing with some Quicktime content on the Internet when I noticed that the Camino browser (I use the 1.0a1 version) is able to save Quicktime movies! Just go to View > View Page Source, find the URL of your movie (<embed src="movie.mov">), and paste that into a new window. Then just go to File > Save As and presto! you're done. I don't know if this is common for all non-Safari browsers.
