I recomend you do not learn the codes. I suggest that you use the undocumented feature the software provides for using Pronto Hex IR codes.

You can find the TiVo IR codes for the Pronto listed in hex format at the TiVo site here:

The details for how to enter these codes into the T2 Theater Designer can be found in the following thread:

Hope that helps out, It did for me when I was learning my TiVo codes. I would suggest you grab my configuration (www.madravings.com) and give it a try, but I am only setup for remote address's one and three. The TiVo defaults to address zero.
