I am happy to report that I have found a website that provides live streaming of several USA broadcast and cable channels. It is not an anonymizer and requires no additional software. Itís free with some commercials, or US$10 per month for no commercials. The quality is sometimes just so-so. I have not observed any buffering delays, but lip sync is often poor.
Some of the channels are ABC, NBC, TLC, TNT, History, Bravo, Current, USA, HBO, CNN, BBC news, and others. Program schedules are not included, but schedules are easily obtained from the online website of each channel.
I wish CBS, PBS and The Food Network were included.
