Glad that worked! Unfortunately, I don't have any "official" list of 842 codes, the "Distance" was just one that I had come across previously.
I do know however that some Onkyo equiment uses a combination of device codes (technically, they use an NEC format IR protocol with two different system addresses), so as you have probably already found out, your unit may also respond to some of the commands in One-for-All setup code 0135. If this is true, I would try the advanced codes listed for that code at Rob's web site (www.hifi-remote.com
) if you haven't already.
