You cannot program a Direct TV receiver with this remote. The Toshiba TV this was designed for was introduced before the Direct TV HD systems came out. This remote does not control any model of DVR. If you want to control both of these with one remote, get a Logitech Harmony remote.
There is no way to change the input without a remote :(.
you dont. go get a remote
That could vary greatly depending on what model of Toshiba TV you have. The link below is to Toshiba's web site where you can get product support as well as replacement owner's manuals, etc.
To program the GE RC24914 universal remote for a Toshiba television, first, turn on your TV. Then, press and hold the "TV" button on the remote until the red indicator stays on, then release the button. Next, press and release the "Power" button repeatedly until the TV turns off. Once the TV is off, press the "Enter" button to store the code. If it doesn’t work, you may need to try different codes listed in the remote's manual for Toshiba TVs.
