Ok, called them, level one support was having a bit of a difficult time understanding what I meant by address 1/2/etc, but was pleasant enough, then she passed me on to level 2.

Level 2 understood what I wanted but still couldn't help, basically she said she didn't have the Address 2 version of Aspect in her database and therefore couldn't add it.

So my options are:

1. Find someone who has a VMC remote with an aspect button as well as a Harmony, get them to change their VMC remote to address 2, add a new device to their harmony, learn the command, then call Logitech and ask them to copy the learned command to my device.

2. Same as above, but source the remote myself and purchase it.

3. Find someone who can determine the hex code of the command (Logitech tells me I can email them the hex code and they'll add it for me)

4. Find software that'll work with my USB receiver (standard MCE) that will display hex codes, chart out what I have for address 1 and address 2, and somehow figure out what Aspect 2 is.
