We just got rid of our DirecTv box and happily returned to Tivo on DirecTv. The remote works great all day and stops working sometime between 6pm and 7pm every evening. We installed on Saturday and it is now Wednesday and this has happened every single day. We also have a a Logitech Harmony remote set up with the devices and it works beautifully all day and also stops controlling Tivo every evening. Has anyone else experienced this? It is as if Tivo gets tired. Then it resets at night and works again until it is again exhausted. That is just my speculation. I believe it is the Tivo itself (or the problem is with DirecTv?) because both remotes work perfectly all day and both stop working at the same time and the Harmony continues to control other devices.
