DirectTV HD-DVR & Yamaha RX-v1500

The types of remotes are as follows

- Single item, or fixed. This unit will only operate the unit it came with
- Multi function, this type can operate the unit it came with and a fixed set of other types. Normally the remote comes with a list of supported device it could work with.
- Learning, the combine both a predefined list with the ability to learn functions by sensing input from the original remote.
- Programable. These are the newest remotes that work like multifunction but the list is maintained by the manufacturer and down loadable from the web.

I would guess that the DVR has a multi function remote.
If you can't find the specific Yamaha in the list, then
try another brand, this could take a while.

Some multi function remotes have an option that allow a semi automatic configuration.
You turn on the item and then using a special key sequence try to turn off the device. once the item turns off you should be able to control it.

If you can't the Yamaha has a learning remote. If you really want an easy solution try looking at a programmable remote. I just got a Logitech, (Harrmony). Life has never been so easy.
