Nope. A source defines the way your tuners work, roughly. Channels are tied to sources and the 
tuning information for each channel is held in the channel record.

This means that if you have a Freeview channel BBC1, say, and a Sky version of BBC1, then they will 
require different information in order to be tuned.

A single source can be associated with a number of tuners, in order to record more than one thing at 
a time, but the tuners must all use the same tuning parameters.
