When I try to fast-forward through a program that I am watching through my cable company's "On Demand" feature, an error message displays:
fast forward and other functionality may not be available...
Why is functionality used instead of function?

Functionality is an adjective which means of or relating to a function or functions.
They might have used this word as they have already mentioned one function (i.e. fast forward). Although, there is no obligation by your cable provider to use correct grammar.
'Functionality' is not an adjective, it is a noun. You can pluralise it to become 'functionalities'. I think 'Fast forward' is functioning here as a verb as in the act of fast forwarding or possibly an adjective e.g. 'the fast forward functionality'. 'Functionality' appears to have a particular meaning when used in the context of technology which implies a range of different system functions. So in this instance, it has a technical meaning. I agree that the cable provider does not have to use 'correct grammar' but we would hope that they make sense.
