Initially I was just want try out the Freeview HD goodness, but turned out couldn't find any channel to watch after purchased a
brand new DVB-T tuner and the whole thing is quite frustrating.

In my bed room where I keep my computers, I tried the small antenna come with the tuner, doesn't work at all most of the time(will cover that later), then come to DSE ang got a amplified antenna L4016, turned out doesn't work either with either PowerCinema and mediaportal (counldn't found a single chennel either!). I am even wandering if I got a faulty TV tuner?

Also tried connect ordinary roof arial plugin to my TV tuner , nothing from either DVT-T or old fashion analog, WTF?

I've used both "ScanChannelsBDA-UK" and "ScanChannelsBDA" and some time it gets not signal at all and sometimes with a strength of 60 and 0 quality or up to 10% in the first software but alternating from 0 to 50% in the second software. What even stranger is looks like either the minim antenna or amplified one don't has much difference in the signal received by the TV tuner, and some times after unpluged from antenna the TV tuner keep on receiving signal. All this things seems really strange to me, and I am afraid even I paid some pros to install a proper roof UHF antenna for me I may still couldn't get an channel at all.

As you can see I am a totally newbiew about the Freeview HD stuff and not really sure what I am doing is right or just been unlucky got a piece of broken hardware.

PS: I am living in St Johns in Auckland and seeing quite a few UHF antenna around neighbourhood and believe it is possilbe to get a good UHF signal in this area. And I do most of my experiments in my bedroom downstairs in a two level house nearby a window point out to west and I believe that is where either Remuere or Waiatarua transmitter are.
