I need the discrete code for switching my 28PT4503 Philips TV directly into "EXT2 Y/C" input. Actually I'm using the "RC5 0 56" code three times . The "RC5 0 56" code is the "VIDEO/TV" switch. Pressing it once it gives EXT1, twice EXT2 and the third time EXT2 Y/C. So I created a macro command giving three times "RC5 0 56". In the Prontoedit list of RC5 codes is reported that the "RC5 0 57" code is corrisponding to a Philips "AUX2" TV but it doesn't works at all on my TV. I' d like to know if there is a discrete code for this command, or a better solution from which I'm actually using.
