I have been using a TSU9600 through a pair of RFX9400s for a long time and everything worked fine. Then I got a TiVo Premiere and eventually a TiVo Roamio. With both of those, every button works great for me except the "Live TV" button. It has no effect.
I have tried a ton of experiments with my old code (that worked on my old TiVo), a few codes from files out here, and learning from the TiVo IR remote. The Tivo remote's Live TV works 100% of the time, but whatever I am doing to learn it isn't working. Everything fails.
Can anyone either offer suggestions or perhaps a code that works? My recent tries were the database codes from TiVo codeset 1267 and 2745 and this one that I "learned".
