SO I've been using my HTPC as the dedicated Freeview tuner for our house, works mint, use it daily.

I have been using the Release Candidate of Windows 7 for a long time, and now just switched to the full release, 64 bit version.

I installed totally fresh with all latest drivers, using Hauppauge HVR-3000 on DVB-T and my nVidia 8800GT 640mb.

I have never had any problems till recently, about the same time as the upgrade to the full Windows 7 Release.. but may just be a coincidence.

Every other channel I watch ( TV3 and C4 ) are mint, hardly ever have any pixelations, TV3 does it sometimes but only veeeeeeeeeery rarely. C4 I can watch King of the Hill and Family guy with no probs! :D

But I was watching several shows on TV 1 and 2 and I get maajor pixelation, it varies from almost every 2-3 seconds to every couple of minutes.

Basically what happens is mainly the bottom half of the screen goes badly pixelated, sometimes black, then returns to normal quickly, sometimes the entire picture will go pixely, or it will skip back a frame like you see someone smile, then it cuts to a different scene but you see them smiling all of a sudden again for a split second while it goes pixely...

I recorded a bad portion of tonights one news that I will upload later on to show.

Any ideas what could be causing this and what I can check. Maybe my antenna has broken? is that possible and how would I test it?

Thanks

Hey,

I haven't look at the video (can;t DL from work) but the way you describe it, it sounds like a reception problem more than anything else. Especially the fact that it only affects TV1 and TV2 (other channels are on other frequencies)
Have you changed anything in your aerial / setup lately?

If TVNZ6 and TVNZ7 do same thing then I'd look at reception as these are all on the same mux.

If genuinely only TV1 and TV2 then these differ from the rest as they are 720P channels.

That info may help?Undecided

Turns out the beast was getting far too hot in the cabinet, I actually physically burnt my hand touching the rear of the case where the tuner was LOL..

So I have modified the cabinet for better cooling and the issues are gone :D
