Request from JT for simple method of printing screen captures of DVD movies.
All vanilla DVD players for Mac OS seem to restrict this or at least not provide simple methods. Many cost money. In the case of OS X's built-in DVD Player, when you try to use shift+cmd+3/4 you get an alert that tells you "no".

To get around this I wrote a simple AppleScript (in Script Editor) that looks like this:
do shell script "screencapture -iWP ~/Desktop/screenshot.png"
"i" is for interactive, "W" is for window (in combination these let you interactively choose the window you are capturing) and "P" is for open it in Preview. The rest is just an output path and file type. Alternatively, you can pass it to the clipboard.
Then I saved it as an application and gave it a handsome icon I made from this.

Here's a zipped copy of the app.
