just a thought, but i've been controlling my Spectrum 210-H DVR for a few years using a raspberry pi that blinks IR using an IRToy. the configuration file i use for the spectrum box is the frequency / pulse / protocol definitions for emulating a standard IR remote. i recently discovered a function that was not in the configuration file. i added it to the config file and i could use that "key"!

the key was the "BACK" button on the Official remote that i never use. it has a "code value" of 0x3E7031

now i'm looking for a similar "code value" for a key that my Harmony Remote system knows about, but not me. the key: LIVE

anyone know how to find this information?
