I have a Sony RM-AV3000 and am replacing my Sony 36" Wega with a Samsung HLN5065W. What I liked previously was being able to use Macro button 1 and 3 to turn all the equipment off or on.

Is there any way to erase the macros recorded in 1 and 3? I'm pretty sure I have tried to do this but to no avail. I have the discrete codes for On and Off for the Samsung and would like to incorportate it into On/Off macros.

Thanks in advances for the help.
