You just won't get the small regional channels over here
You may have been looking at the DOGs, but not the name or content. That's CNN-I (International), NBC-Europe and FX-UK, so not American channels, but Europeanised clones of their US namesakes. Fox News, I'll give you, but it's hardly mainstream US content.
As for others, well there's goodies such as Hollywood TV, Real Estate TV, The Poker Channel and The Wrestling Channel. Lot's of US content there of course, but nothing that will really float your boat, unless you are particularly sad...
