No home broadband is going to be truly unlimited but after a year on cable I can certainly say it has a whole lot less in the way of limits than most ADSL packages I've had.
I find anything less than the highest quality iPlayer streams virtually unwatchable on my pretty average size 42" TV so avoid using iPlayer as much as possible by remembering to record anything I want to see which I can't watch when it's broadcast - old fashioned I know
