It's easy to tell if your Tivo is affected by the suggestions bug by simply checking the suggestions list. If suggestions are enabled and the suggestions list is permanently empty but will populate with the tuning adapter disconnected, then your box has the Tivo software bug. If your suggestions list is populating but the actual recordings are failing, then you might be the victim of a denied speculative tune by your provider. This type of failure will show in your recording history. Tivo Margret has announced a planned fall update for the Premiere line for this suggestions and tuning adapter issue. I doubt we'll ever see a fix for the HD/S3 platform.
