Need to export to a folder on Desktop named "movies"

I’m trying to make a 2 click podcasting script that will open QT Pro, start recording audio till you click Stop and export as MPEG-4 to a folder on my Desktop named “movies”. The only way I’ve gotten it to work is putting:

set targetFolder to (choose folder with prompt “Choose a folder in which to place the converted video file before importing into iTunes…” without invisibles) as string

But, I don’t want to have to choose a folder. I want it to already know to put it in that folder. And it needs to work on any Mac I run the script on (providing that folder is created on the Desktop. I tried:

set targetFolder to “Macintosh HD:Users:Pat:Desktop:movies” as string

but no go. What would be the proper way to address my “movies” folder on the Desktop?

This line of code should work on any machine:

set targetFolder to (path to desktop as unicode text) & "movies:"

Thanks, Craig. That worked great!
