The first device I programmed when I finally received my MX-1000 was my TiVo on the AUX device. I tried the published code for "Tivo" but it didn't work at all...so I designed some screens with the PC software and proceeded to learn the codes...

Well, it's going well, for the most part. But strangely when I learn one code for a button, another one quits working. I can recreate this problem reliably by programming a TV power button (for my Sony TV) and the code for the "TiVo Central" button quits working...or rather it starts working as another button. This sometimes happens with other buttons as well. I haven't seen any problems with the hard buttons at all, their learned codes seem to stick.

Has anyone else had this problem with TiVo learned codes or other devices? Am I doing something wrong? I haven't yet tried setting up another device, but that's what I'm going to do next and see if I have similar problems or if it's just related to AUX/Tivo.
