No, this is because TiVo has a function called Suggestions which records programs it thinks you might like.
You should turn Suggestions off.
Thanks for your post and apologies to hear your TiVo® is recording things you're unaware of.
Double check the Suggestions feature as sometimes a new update can turn this back on.
Also, have a look to see if there are any wishlists created. If you've created a wishlist for a certain actor or genre then this could be causing the box to record things you're not aware of
Keep us posted.
