I have a Harmony one remote controlling a Panasonic plasma with direct line of sight, and a directv hr34 dvr and sony DTS 1030 reciever in a utility closet using an IR emitter. The directv dvr will not power up initially through the emitter. Using the help button will power it on after the other componants have come on. All other commands work appropriately, and all other equipment powers up appropriately. The box will power on if it has line of sight. Can anyone help?
