Quick update: I did a complete scan of all 256 code and found some new codes (hue, sharpness, color, status on / off / show, DDE toggle, picture mute toggle, etc.) However, I did not find any discrete codes for aspect raito. I guess using the User 1-3 presets is a close as you can get.

I submitted the PCF file with all of the codes to the files section here at RemoteCentral but it is not up yet. In the meantime, it can be downloaded from my webpage: [Link: carltonbale.com]
