The 2010 version of DirectRT should have no problem running this experiment; however you'll need to reference the actual video file, rather than a web page.

As Blair has noted, DirectRT 2010 has the ability to continuously monitor the keyboard.

If you would like, I could help you get started with a trial version of the software. I would be happy to work with you to get your experiment up and running. Send over an email to our support address for more information.
