I'm running EyeTv Elgato Hybrid, and most of the time everything works fine but from time to time the TVNZ channels start messing up, the audio runs continuously but the video starts pausing and getting all these green artifacts, I check the signal strength and the TVNZ channels drop to around 40% whereas it is usually at 100%. It seems to come right eventually, but does anyone know what is actually going on or how I can fix it?

Signal strength will depend on transmitter (TX) power, distance to transmitter, obstacles between you and it and the receiving antenna. What city do you live in?, or failing that what UHF channels is DVB-T signal on so that we can determine where you are receiving your signal from. What type of antenna do you use for reception (maybe you could take a photo), where does the antenna point, what is analog UHF reception like.

I live in Newtown in Wellington and in a large apartment complex, the antenna is on top of the building and is facing a north east direction. The antenna isn't exactly accessible and there are actually a couple on the roof but I'm pretty sure of the one that supplies my flat.

Didn't understand the  "what UHF channels is DVB-T signal" part of the question.
Today the signal for TVNZ (1, 2, 6, 7 and SportExtra) channels is even worse.
Here is a picture of what my antenna looks like UHF Antenna

It all became clear when you said "apartment" - the antenna system will not be set up to pass the channel so you are just getting leakage into the cable.

Complain to your property manager that the antenna isnt working for freeview HD and to please sort it out.

Thanks for your reply. If you don't mind would you please explain the problem a little for specifically and simple so I can go to the property manager convincingly. Cheers.

As well as picking up what you want, antennas get a crapload of noise, so they install channel filters to let thru what is wanted and block the rest. Everytime a new channel starts, they have to have a filter installed to let it thru. Its called MATV and there is heaps of gear needed to deliver a good signal to heaps of outlets like in apartments.

houses dont have the problem because you dont have to put the same amount of amplification onto it when only going to 4-12 outlets.

Do you know why the signal has gotten worse over time. I got EyeTV about a month and a half ago and for the first 3 weeks it worked flawlessly but then occasionally the signal would drop to 40% and I could pretty much only get audio, and then this past week the signal has dropped to 0% and I don't receive anything? What would have caused this and is there any way to improve the signal myself?
