Any one else having a problem with all the channels broadcast on the kordia mux. Prime, Maori etc

My LG TV (built in DVB-T) is getting picture but no sound.
My JC Matthew receiver is get sound but no picture.

Both are reporting good and stable signal strength and quality so I'm assuming at this stage its a transmission problem. Would just like to confirm if anyone else in Dunedin is also having a proplem.

All non kordia channels are ok.
