This seems to be a major oversight in the Hulu Plus app. On the app home screen you cannot simply navigate to your Hulu queue via voice commands.
The initial set of commands only allow you to scroll the masthead display or move to the lower rows that do not contain the queue. Saying 'DOWN' twice then 'UP' will allow you to access the correct row. Once you select your queue, however, you still cannot select shows that are in its second row and cannot scroll down.
This is all a major inconvenience so I am posting it here in hopes that it will be fixed in an update. I am paying for this service after all.
