Now, on the off-chance that this is related, here's something I found

In fact, this is not a problem related to QuickTime
as-is. This is a problem with the CD driver --- if there is no CD in
drive, then it seems Apple probes the drive every ten seconds or
something, and if this happens during an async IO that QuickTime is
any other program, mind you) then the freeze will occur. Solution?
Leave a CD inside your CD-ROM player. Audio or data CD, it doesn't
matter. As long as a CD is mounted on the desktop, you won't suffer
from the problem.
I first experienced this problem while using Anarchie during
long FTP transfer, and reported the problem to Peter Lewis who told me
this. I was then able to duplicate the problem with about every other
software, mostly those who do long async IO operations...
