Sometimes I check on my TiVo box and find that there is a Suggestion recording. If it's not something I'd be interested in, I select the recording and click Stop (not stop and delete), as this stops it moving into Recently Deleted.
If I do this, the TiVo box then starts recording the SAME show again on the +1 version of the channel! Is there any way to stop this behaviour? Do I have to give Thumbs Down to a programme whenever I don't want it to record on Suggestions? I don't particularly dislike the shows; I just don't want them recording all the time...
Sorry to hear you're having trouble with Suggestions.
If you don't want that program to record, go to Home, My Shows and Recordings, My Shows then Suggestions. You can the select the recording and press the Thumbs Down button. Using the Thumb ratings will improve the suggestion the TiVo® records.
