Sorry 3FG for the delay of my answer, I was out of town for a while. I wanted to thank you for the time you took to answer me. I really appreciated.

I will look for the suggested remotes.

I have to more questions:
1- With the RCA RCRP05B and the Sony RM VLZ620, is it possible to control the sound of the Harman Kardon matter the device selected? For example, the remote control the Blu-ray but the volume button passes the info to Harman Kardon.

2- Are buttons of those models backlit?

If an answer is no, do you have another suggestion?

Thanks again 3FG,

Asimov
