Am I the only one experiencing this? For at least the last 2 hours all the Discovery MUX channels (Three, Bravo, 3+1 etc) here in Christchurch have being exhibiting strange behaviour - On the the 10-year old Sony Bravia that my Mother uses the screen goes black when switching to one of the channels then the TV pops up a message saying the channel is scrambled or data is corrupt..eventually a picture comes up but is about 12-15 seconds behind the audio. The picture will freeze up after a few minutes then re-start again, still out of synch. On my 5-year old Samsung (on a different antenna) its manifesting as an audio drop-out every 5 seconds and the picture being slightly out of synch with the audio. Tried all the usual things without joy..seems to be at the broadcast end.
