Spam? From me? I feel insulted!
I saw the title before I saw your name! :lol:
On Freeview I have your basic 5 channels of course, then:
BBC3 and 4, BBC News Channel, BBC Parliament, CBBC, Cbeebies
ITV2, 3 and 4 (and all the +1s)
E4 and More 4 (and all the +1s)
Fiver and Five USA (or whatever they're called now)
Pick TV (which used to be Sky 3 I think?)
Dave, various music channels, QVC, Price Drop, Bid Up, Ideal World etc
Film 4
Four HD channels (on Freeview HD)
Lots of other cr@p (history channels etc).
None of your "main" Sky channels though. No SyFy or Horror Channel (unfortunately). Certainly no sports or film channels. And no UK Gold or UKTV Food etc.
It's plenty for me, but you might miss your Sky One, Sky Atlantic etc.
