The wonderful BBC have finally managed to bundle together a version of iplayer that allows you to download your TV for up to 30 days. It’s still DRMed, using adobe flash and adobe air to give you the iplay application outside your browser.
Follow the link below, to the labs and click the button to enable the labs features. Go to you favourite show, and click download. You will be prompted to install Air etc, which takes a couple of minutes, but after that the download starts and the world is your mollusc.
