Just in the last few days I have started to experience lousy picture and sound on Prime/Maori/Stratos/Trackside/Parliament/ National Radio/Concert Programme/TV33/TV28(Chinese)

The picture and audio break up and make it impossible to watch the programme. Sometimes it seems as if another channel is trying to come through on the one selected. eg when trying to watch Parliament it seems as if Stratos is also coming through behind Parliament? 

I am getting good reception on TV1/TV2/TV3/TV4/U/TV7/TV3+1/C4


We will be getting our signal from the Waiatarua transmitter 

Although in the past I have had intermittent problems with TV3, but at present it seems to be OK.

I have checked my signal strenth on TIVO and all channels are around 81 to 83%   


This is happening on both my TIVO and my Zinwell decoder, so it is not a problem with a device.

Help

P.S. I guess I should mention that I am in the Opaheke area of Papakura, South Auckland
