Hi all,

Wondering if anyone has any ideas to fix a picture problem.

I have Freeview HD via Media Portal with an HVR3000 anf Asus nvidia 8500GT. I have a direct line of sight from my aerial in Wilton to mt KauKau in Wellington. TV3, C4 are perfect no issues at all but TV1 and 2 both have issues where I get funny pixels every so often - although sometimes it will go for half an hour with no problems.

I have replaced my cable to the aerial to get rid of a join but that hasnt helped. The aerial is one of the standard type that Sky used to install for UHF, its a bit rusted but otherwise looks ok.

Do you think its worth buying a new one? perhaps a high gain aerial? or could it be something else as it only seems to happen on the 720p channels?

I have stopped using DVB-T for 1 and 2 in the mean time - using DVB-S instead - but it would be great to get it working.

How big is the aerial at the moment? If you plug it into a tv what kind of recption do you get on Prime, Maori TV and Trackside?
I found that when i had a bad aerial i could only get Kordia Channels then some adjusting i got Mediaworks and Kordia, but i needed a bigger aerial in perfect alignment to get TVNZ channels. Also with the bad aerial i got stuttery channels on all Kordia and Mediaworks channels. ( I am in quite bad coverage area for UHF though - even though in east auckland in heavily populated area)

Its just a standard medium gain aerial. I havent tried it as a normal TV aerial - only plugged into a DVB-T card. I might give that a go and see what the results are like.

If you get clear pictures on those 3 channels it is quite unlikely there is anything wrong with the aerial. But if they are snowy then you may want to conside realigning the aerial or getting a new one.
