Does anyone know the code for the Yamaha RX-V663 remote (the actual model is RAV 285) to control the DirecTV HR21-700 (the black HD DVR)? None of the codes in the Yamaha manual for DirecTV seem to work. I also made sure that the DVR is set to IR, not RF, remote.

The only oem remotes with a preset code for the current line of directv receivers are only made by UEI, and if it were made by UEI the code would either be SAT 1377 or 01377.

UEI is the same company that makes the white directv remotes.
