We're hesitant to say that the flood gates are open, but it looks like AT&T is pushing its Total Home DVR software out at a pretty regular clip. Just days after introducing it in the Bay Area and merely hours after dumping it on Dallas / Fort Worth residents, AT&T is now bringing the U-verse update to customers in Los Angeles, Fresno and St. Louis. In short, the software refresh enables users to play back any recorded SD or HD program on any connected TV in their home at no extra charge. Who's up for placing bets on the next locale to get the good news?
