sethos,
Hi. I have this information for the SR5300, and it should be the same for your SR-82, but it is in a Device Combiner format (jp1). I will look at it tonight when I get home, and if nobody provides the correct information before then, I will see if I can get you a device code and advanced code. The trick might be that the device code may not be in your remote, as the input commands for these receivers typically use something other than the 0269 and 0189.
If nobody has helped by tonight I will try to, and will explain further.
Jim
