When I turn on my Yamaha RX-V673 receiver using its remote control the Echostar stops responding to the remote and I have to do a factory reset to get it back. A real pain having to go through the procedure and set up the recordings again.
Has anyone else had other manufacturers remotes causing issues?

No need to reset the box - see the second comment on this video...

Thanks for that 2Bdecided

I now have the solution from Echostar.

Every time you press the power button on the Yamaha remote, the Yamaha remote sends out a pairing address command (address 126). This sets the Echostar STB pairing to 126 also. As the Echostar remote is most likely set to a different pairing it no longer responds.

Reprogram the Echostar remote with same address as the Yamaha:

Do the following on the HDS600 remote:
1) press and hold the left and right arrow keys for five seconds (until LED stays on)
2) Using the numeric keypad, enter digits 1 2 6 (LED blinks three times)
3) While pointing the HDS600 remote at the STB, press and hold the right arrow and OK keys for five seconds (until LED blinks 2 times).

Problem solved.
