Hy PaulG,
It's not true that you can't house a satellite tuner on a Raspberry Pi.
Take a look HERE, perhaps this is a solution for you. It's been recommended here several times before. Before you consider buying it, please note that shipping may be from abroad, depending on where you live, and could take a few days depending on availability. This is just a side note.
And regarding Freeview Live TV (IPTV), take a look HERE.
I hope this helps a little bit 😉
