I have a Toshiba Series 2 SD-H400 with TiVo Basic. I have the Scientific Atlanta Explorer 2100 cable box. I use an IR blaster to change channels. My cable provider is Cox. Yesterday TiVo froze while I was in TiVo central. No matter what button I pressed on the remote it wouldn't budge. I unplugged it, plugged it back in, and it was working again. But now, it no longer changes channels. The screen shows TiVo changing the channel at the top of the screen, but the cable box is not receiving the information and actually changing the channel. I'm sure everything is plugged in the way it's supposed to because all I unplugged was the TiVo power cord and plugged it back in. I could've sworn the "Bypass" light on the cable box was lit before and now it isn't, but maybe I'm wrong and it wasn't lit before so I'm not sure if that had anything to do with it. What could the problem be? Thanks for any help you guys can provide!
