My other half was watching that god awful Dancing with the Stars last night in bed.  Set up in bedroom is a DSE (Zinwell) Freeview|HD box connected to an outside aerial in an apartment block.

At approximately 10:25pm last night, and for the first time in ages, the picture and audio started to stutter and break up, but only on the TVNZ channels (1, 2, 6, 7 etc).  TV3, Maori etc were fine.

So I trudged downstairs to my HTPC to see the Freeview|HD picture on there (hooked up to the same outside aerial), and got the same stuttering on only the TVNZ channels.

This has happened in the past, but not for quite some time.

I live in the Freemans Bay/St Marys Bay area.  Did anyone else have any issues last night?  What what what is causing this???
