We get this a lot by email and by phone: My TiVo is responding to my remote very slowly. I think my remote or my IR board is bad. I’ve changed the batteries and rebooted the unit.
We’ve got a strange answer for this, but it’s the right one almost every time: IR interference.
For some reason, TiVos are unusually susceptible to other IR waves. So other remotes, IR blasters, and other products can cause this behavior. Half the time, there’s a remote jammed under a couch cushion with a button stuck down.
So we tell people to just take all of the other remotes out of the room, and see what happens. That almost always does the trick.
The key way to know if this applies to you? “My TV still works fine with my TiVo remote . . .”
