I've been having some problems with my cable provider, and I'd really like to subscribe to an IPTV service. Certain features sound very intriguing, but I'm not sure how "seamless" the transition to television via IP would be. I know SBC and Verizon are supposed to be rolling out services this summer, but does anyone know where that will be? Or if there are technical glitches that need to be ironed out? I really don't want to have to wait to switch channels like you do with satellite. Thanks
