Patrick, a quick note on this (not sending to list).
If I'm not mistaken, this quote from the YouTube TOS explicitly forbids
downloading videos unless there's a download link there, provided by
YouTube (as opposed to by a Greasemonkey script, for example):

So I suggest you avoid this sort of (apparently) unethical behavior.
