I live in Christchurch (just north of the CBD) and we have near-perfect pictures on all analogue channels except TV1. Sometimes it is fine, but often (particularly in the mornings), the picture is extremely poor - sometimes completely unwatchable. We've been watching a few times where the picture has been fine and then it suddenly goes bad (so bad my TV gives me its very own BSOD!).
Just wondering if anyone out there has any experience of this - the fact that all other channels are great suggests to me it's not a problem at our end, but I could be wrong.
Any suggestions / insights welcome!
