Is there any way to watch live TV on a laptop? Not like HuluPLUS and the like, but to for example leave it on during the day for company for a pet while I'm at work...or if I just want to channel-browse at the end of a long work day rather than having something particular in mind? The specific channels I would be interested in, if it matters, would be things like Animal Planet, BBC America, the Weather Channel, and local/network.
