Hi

This doesn't seem right. I thought 720p should be harder to decode than 1080i or have I got this wrong.
I'm running Win 7 32 bit and MCE using a Winfast DTV1800H Tuner on an older PC with a AMD 3800+ and a Nvidia 8600GT.

Any advice would be greatfully accepted

Different frequencies for TVNZ channels and Canwest... Maybe you have a reception issue fo the frequency (mux) that the TVNZ channels are on.

Check out my LPFM Radio Station at www.thecheese.co.nz - Now on iHeart Radio, TuneIn and Radio Garden

I have the same issue with Freeview. The signals come from different directions. To get Canwest content, I use bunny ears oriented toward the kitchen windw (Auckland CBD) and the to get TVNZ I use a rooftop antenna pointing about 60 degrees to the right of that. I have to swap the antenna cable connections to swap between the groups.

I'm now living in a house in a dip with marginal reception. At our old house Freeview worked fine for everything, but there we had more or less line of sight to any transmission source on the other side of the Waitemata harbour.

1080i is the most difficult signal being both highest resolution and interlaced.

720p progressive should be much easier to display for your hardware. You could use task manager to check CPU utilization during windowed playback to see how hard your system is working.

Where are you? As has been said TV1 & TV3 are on different frequencies on Freeview-HD.

HTPC: Antec Fusion 430, Intel i3, Gigabyte 1050, Corsair 4x1Gb, Hauppauge WinTv, Logitech z-5500, Logitech Harmony 525, Yamaha Rx-v6a, Samsung KS8000 4k, Windows 10, Mediaportal 1.30, BLU-RAY: Panasonic UB820

I figured that this is the case. I just thought that if you could get one that you could get all.
Having said that is this just a case of a bad signal and so there's nothing I can do - the aerial was professionally installed

Hi thanks to those who oferred help.
I've figured it out. MCE finds manya number of different frequencies from different transmitters for each channel. It then seems to get confused which one to use. By playing around with the "Edit sources" I was able to select one that worked fine
