Older basic Freesat boxes certainly had a manual tune feature, don't know if the newer Freetime ones do.
It’s an EU requirement I think ?
Yes, the Freetime boxes do have the option to tune in channels manually, but (on my Humax box, anyway) hidden away in the menus and deliberately clunky.
I thought that Channel 4 had brought back the old Simpsons Ident from 2004-15.
But they’re actually showing the episode where it appears as the couch gag.
Did the 4 form up at the end or was it removed?
It didn’t form up, but obviously you can still see the outlines of the roads and such making it out.
