We've got a VHF aerial, 720p plasma, and I just plugged in a new freeview HD box into the flatscreen via the supplied RCA cables. All channels are noise/snow free. BUT the picture's slightly pixellated with noticeable "jaggies" - especially on diagonals and curved lines.
1. Do I need to use HDMI cables to get rid of the jaggies?
2. Do I need to change to a UHF aerial - given all channels [Prime/Maori/TVNZ 6 + 7] are coming in strong?
Cheers in advance
