Those instructions just show you how to get to the TiVo Suggestions screen, but they are missing a minor detail.
Once you get to the Tivo Suggestions screen, you can press 'Enter' on the remote and review *all* of your thumb ratings (at least that's the way it works for the S3 platform).
Edit: Thanks for making me review my suggestions list. There's an upcoming F1 race that was in my list. Set to record.
