Hi all. I am trying to create a HD/SD macro for HDTV on a Mits SRHD 400. It consists of pressing action then input. I learned both codes but if I am in HD mode it will go to SD. SD automatically sends the signal to another input on my TV. If in SD I can't get the switch to HD which is the same macro. I even have the macro hit DTV input on the tv first, then action, HD/SD and still no go. I am probably missing on something simple here. Anyone eperience this or a have way to be able to switch back to HD? I would hate to think I need to use the Mits HD remote just for this one control. Thanks for any help.
