Yep...I figured that out just a couple of minutes after posting this question. I gues I should have RTFM better :). Thanks for the help.

tkrug,
Since you appear to be very knowlegable about this remote, can you tell me if there is a way to guess at discrete codes if you know others used by the device?

My problem is this, I have an AKAI plasma model #PDP5016H. I was unable to find any codes that would operate it so I simply "learned" the codes I needed. The orignal remote however has a toggle for on/off and select the input source from a list. I need discrete codes for both the on/off and the various input souces. So the question is, is there any way (knowing the codes that I have learned) to make an educated guess at the discrete codes I need. In other words are the codes for a particular device generally all within some range of numbers and therefore I could simply determine which ones are left out after learning all on the remote and try those.
