I recently "upgraded" my cable box from a Scientific Atlanta 3100 to a 3250HD to take advantage of Hi-Def programming. In the past my TiVo has been 99% accurate when it comes to changing channels. I am having a problem with this new box that I just cant seem to identify. Basically what is now happening about 20% of the time is as follows: when I enter a channel (say 405), the cable box will see channel 4, then hesitate, switch to channel 4, and then recognize the -05, switching to channel 5. Of course the TiVo thinks it has switched to 405. When this problem happens, the error is always after the first digit. I have reviewed other posts and tried everything except switching the cable box (that's next). I have constructed 2 different tents, tried using one emmitter instead of two, varied the distance between the emmitter and the cable box, tried codes 0018,0048,0049 (Fast, Medium, Slow on each), and have also used two different IR emmitters. I also tried rebooting the cable box. I am at a loss. Before I return the box and have to try to explain my TiVo issues to someone who doesn't know and/or care, I was wondering if you all had any suggestions. Also wasn't sure if anyone else had issues with this box. Any help would be much appreciated.
