Well, I'm glad you were able to capture your codes a_tivo_noob. There are quite a few posts about what set top boxes are compatible with an S1 TiVo, so I was a bit surprised there was not more interest in this method of capturing codes, which makes all boxes compatible.
Using this script you can get the codes for ANY set top box (as far as I can see) provided you have the remote and the STB to test on. I helped a friend who bought a new Freesat box (can't remember model) that wouldn't respond to the TiVo - captured the codes and it is now working fine. I also have a completely non standard setup with a Technomate TM1500 to watch foreign channels and a Digibox for Sky and the TiVo handles that, as well as my digibox without any problems.
If required I would be happy to write a more complete "Capturing IR Codes using irSliceCreator" guide.
It might also be worth having a sticky where codes for specific STB models can be posted so that once captured anyone can use them without having to go through the process themselves.
