Dealing with several different remotes can be more than just a little bit aggravating. Often times you will find yourself with two or three that no longer have an obvious use including one from a VCR you owned in 1989, which you sold to your aunt last May (may she rest in peace).
One question that some have asked is whether it is possible to use a Tivo remote with a DirecTV HD DVR. The answer depends on the shape of your Tivo remote as to how easy it can be to do so.
The interesting thing is that DirecTV/DirecTivo use a remote control with a peanut shape. These remotes are interchangeable. If your Tivo remote is shaped like a peanut as well then you will find programming it for your DirecTV HD DVR will be quite easy. There are only a few steps in setting it up and you will be ready to go.
