Search your receiver's Guide for "BBC World", it is carried on a number of channels, including most PBS, as well as BBC America.
It is only a half hour news program, it is far less in depth than CNN, although it is a good compliment, because it is less US-centric as covers Congo, Sri Lanka, etc. If you have a DVR, just tape it when it airs, having the channel full-time is not much help as they tend to repeat the same stuff all day.
I am gravitating more and more to CNN, because the best thing is to have first hand information. I hate when journalists say " The President today said ", rarther than just giving you video of The President (whether the previous one or the current one).
I was annoyed yesterday when CNBC showed a little video of the first White House Press Briefing of the new administration with reporters talking over it, so I changed over to CNN who had the entire thing uninterrupted by either journalists or commercials.
I'm also inclined to switch off any channel that talks about Natalee Holloway, Scott Peterson, Caylee Anthony and any similar non-news "features".
CNN and BBC both have their bias and slants that one needs to be aware of (a web search will easily give more information), but they tend to be more hard news than the alternatives.
