If you have not already subscribed, you should see a prompt above to subscribe to the Ubiquity iPlayer command feed. If the prompt doesn’t appear, try opening this page in a new tab – don’t know why but this sometimes makes it appear.

If you can’t access the “watch” or “listen” commands after subscribing use the “help” command in Ubiquity (or visit “about:ubiquity”), then go to “Your Commands” and make sure they are both selected.

If that worked OK then read more about how to use it on the homepage.
