There are some options out there from what I have read, but wanted to get some input from those who have had experience watching BBC content in the US.
They have it on Direct TV.
I do not know which Cable TV companies have it but since Direct TV is owned by AT&T it is also probably on U-verse as well.

'BBC America' is a very misleading name in any case, since half the stuff they show isn't even produced by the Beeb, including aforementioned Ramsey shows.
