I know this has been asked before numerous times. I just finished checking the forum answers but I just want to verify and possibly get more answers/help. We switched to Verizon FIOS a month ago. I ran setup with TIVO DT2 and everything was working fine. Now all of a sudden we lost the signal for our basic cable channels to the Tivo. Everything going to the cable box works fine. I restarted the Tivo this past Weds. We got the channels back. But lost them again on Thurs. I again restarted the Tivo twice yesterday and still no basic cable channels. All the connections are good. What else can I do? Do I need to buy a booster for to attache prior to the splitter or after the splitter to the Tivo directly? If so where to buy booster, Radio Shack?
