I just finished watching charlies angles in HD with 5.1 audio, via my new SA explorer 3100HD cable box! time warner tampa bay has finally stepped up and has begun the rollout of HD STB's to consumers! picture is nice (comments on HBO's cropping withheld ) sound was fine. they are sending out hbo and showtime currently, but they tell me that local network programming is "comming soon" along with other hd feeds like discovery channel. whoppee! i have HD cable!
