If you don't want it, I'll give you $10 for it.

Seriously -- these are all known problems. Read the FAQ

1) Put fresh batteries in your remotes before trying to use them to teach codes to the Pronto. As batteries age, the codes they emit are still good enough to trigger your electronic devices, but corrupt enough that they givebad learns (and give learns that can vary from one press to the next).

2) Codes will be better learned with the Pronto disconnected from the PC

3) I use the pronto connected to the PC using prontoedit, but only as a starting point. There are a number of very good utilities out there that will determine what type of IR code it is, and what the device and command number is, and which will generate "clean" copies of the hex code. I take the learned code, determine what it is, generate the clean code and paste it into my CCF.

If you don't have any experience with Pronto utilities, I suggest you look at this thread [Link: remotecentral.com] for details on how I got started with IR Tool and Make Hex to generate "clean" IR codes.
