I have not used my TiVo since I had AT&T U-verse installed several months ago. Set it up Friday night to a non-DVR set top box (Motorola 1200). The TiVo took a while to update, and then I entered the magic channel changing IR code of 10081B, tinkered with the positioning of IR blasters, and then everything was hunky-dory. I could see live TV, the IR blaster was changing channels just fine, etc. Only problem was that TiVo still had the channel setup for the AT&T Dish Network I had months before. So, I went to the channels section to set up my new lineup. TiVo connected to the server and took forever to update since it had been not used for so long. Woke up Saturday morning, and TiVo walked me through choosing my U-verse channels - looked promising. BUT - I noticed as I was verifying channel setup that I could no longer see live TV through TiVo at all - just a black screen! No settings, channels, or connections changed on the TV or U-verse STB overnight - the only thing that happened was that my TiVo box updated itself - now NO VIDEO. What gives? The troubleshooter just says check connections. U-verse box is still working great on its own. Please help! So close, but yet, so far......!
