I have been using a TiVo as a STB flawlessly for abt 2 yrs. Recently I had problems which forced me to reinstall Win 8.1. I an using a Hauppauge Colossus with the TiVo. I recently found out that I can control the TiVo via TCP. I have it set up and working perfectly in the TV Server config tests, but it will not change channels using the guide. Looking through the log, it seems to be issuing the commands properly, but not sure where it goes wrong. Any help would be great.
