I have a Humax Tivo Series 2 that is connected to Comcast. Up until January the system worked fine with a six-year-old Scientific Atlanta analog box. When that box went out I took it back Comcast and had it exchanged for a Cisco RNG-1000 digital box. In resetting the Tivo I used the Scientific Atlanta code since no Cisco code was there -- no problems then. However I now occasionally find the cable box has turned itself off. This never occurred with the analog box. Last night this happened while I was watching another recorded program. I tried to see if using the Series 2 remote caused this. I got some dimming in the Cisco "power-on" LED when I pushed some buttons, but it did not turn off. There is no set interval that this occurs -- it seems to be pretty random. I have three questions: Is there a IR conflict between the Cisco RNG-1000 and the Humax Series 2? Is there an alternate code at setup that can be used for the Cisco RNG-1000? Is there any way to set up the remote (Comcast Custom DVR 3) to operate the Humax? Thanks in advance for your help.
