Soundbar Remote Programming

Just purchased SurroundBAR SDA. I can program my TV remote for volume UP and volume DOWN - works fine. I can't seem to program MUTE or POWER - I always get the flashing red light. I've tried other remotes (TiVo for example) and same result - volume works fine, MUTE & POWER fail.

Any help would be appreciated.
