Just as a side note, this program came about because of the people on AVS Forum (www.avsforum.com). Here's the original thread, with a truely absurd number of replies: [Link: avsforum.com]

I believe the discrete codes are the same as what PHSJason has previously posted here (and there). But here's some other information (from the above thread):

The discrete power on/off may work for newer sets with the latest firmware. The input selects appear to only work on upgraded sets (and presumably the forthcoming 467/567). If you have a recently purchased set the upgrade may be less than $200.
