Thanks for the response, John.
I continud playing around with my app, and I don't seem to be having this problem that often anymore. The main difference seems to be that I'm working in a different room, though it's not clear to me why that would change anything. Perhaps there was a lot of IR noise in that room? I've also had a bit more time to play around with the .NET wrapper, and it may just be that I'm dealing better with its quirks.
Now I have a new problem. I've gotten my app to work fine with most of the remotes that I have in my system, with the exception of the remote for my InFocus ScreenPlay television, which is the same as the RCA Scenium HDTV described in a different thread in the Troubleshooting forum. For this remote, I seem to quite often get different codes for the same button press. For example, for several presses of the "Input" button I got this sequence of codes:
678805051EF0
678805051EF0
3305051800F0
69070B0583F0
678805051EF0
678805051EF0
Note that this is just coming from the receive callback and I'm not doing any learning. Several particular codes appear often, usually in contiguous blocks, such as the 678xx code above. I've also seen the 3305xx code often, but all of these codes are interspersed with other seemingly random codes. The system definitely seems to report the same code more often when the button is pressed in rapid succession, but unfortunately that is not the usage scenario that I have for this remote.
There is one difference between this remote and my others, though I don't know if it is important. Unlike all of my other remotes, this one does not send a continuous stream of codes if you hold the button down. It seems to only send one code per button press.
Is there any way, perhaps computationally on the PC, that I can determine which of these codes are the same? I would try to record each of the codes that each button generates, but I fear that this would take a long time and might not be complete.
Thanks,

P.S. Right now, I'm trying to build an application that records all of the remote control activity for my home theater. Thus, I need to be able to recognize every button press on each of my remote controls.
