Originally, I had Vista (64 bit) running Freeview HD working fine on the WinTV 7 application that comes with the Hauppauge TV tunder Card. I was happy with it - but it would not resize to a small size so I can have it on the side of the screen. I wanted to use Windows Media Centre - which allows resizing of the video - but it did not pick up any of the digital channels on the DVB-T tuner with the old Vista (probably not being able to use the H-264 that shiopped with the tunbder card) - though it picked up the analog channels - but the quality was not as good as DVB-T.
So I upgraded my machine to Windows 7 (64 bit) Premium.
And to my delight, I could pick up the digital TV channels from DVB-T tuner from Windows Media Centre.
The pictures on TV1/TV2/TV3 was fine 99% of the time.
But C4/TVNZ6/TVNZ7/TV3Plus /TVNZ Sports etc. shows up in Green
To get an idea of what I mean, check out the following screen dumps - one working, one half working / one not working.



What is also weird is - I can record it and play it back - and it no longer Green like the above. [Edit - It does the same when you watch recorded stuff back too]
But when you watch any channel apart from TV1/2/3, it is unwatchable live.
It cant be the signal - I have an external aeriel - and the signal strength meter shows the following:

I just upgraded the disaplay driver(latest from ATI) and latest tunder driver (latest from Hauppauge) - but the problem persists - anyone came across similar issues with Windows 7 MC?
