niekerkj:andrewNZ: If picture quality is important, Terrestrial is the only real option. Satellite picture quality is poor at best, and you'll get rain fade in bad weather.
So how bad is the picture quality of DVB-S? Will it be totally unwatchable on a 40" LED?
No, I think the Freeview DVB-S Stream is better (less compressed) than the SD streams you get from Sky.
DVB-T is much better for the HD channels though (One, 2, 3). DVB-S will still be quite watchable though.
If you have MySkyHDi, watch a show on One (or record it), then compare it to the same show on One+1 (about Sky 501 I think?). That should be about the difference.
