Following on from this post: http://www.geekzone.co.nz/forums.asp?forumid=84&topicid=31873

I got a new card from my supplier, same model. Chucked it in, and now I can watch TV3 in HD with only occasional glitches. However it's still not doing hardware decoding - CPU is managing to stay under 100% most of the time, but never below 90%.

I am wondering if it could be because my mb has only a PCIE-1 slot, and of course the card is PCIE-2 - I was of the understanding that there was currently no difference bewteen PCIE-1 and 2, it was just that PCIE-2 is faster, but 1 is compatible with 2 and vice versa.

Is anyone getting Windows 7 to decode in hardware HD video on a graphics card plugged into a PCIE-1 slot?
My ATI 3450 card did hd decoding on the same mb and PCIE1 slot...

Any thoughts anyone?

Have you tried intsalling WinXP or Vista and seeing whether you can do HW decoding? That'll at least narrow down the cause of the issue to hardware or software.

Windows XP I know of, but what's this Vista you speak of? :)
I had an ATI 3450 installed, and this decoded the same video in hardware (CPU used 1% or less), trouble with the ATI is that while it worked great for Tv1, 2 and 3, it screwed up with channels like C4, tvnz6 and 7 for some reason, which is why I bought the nvidia.
It will Hardware Decode in WinDVD 9, I'm pretty sure, altho not entirely convinced because WinDVD 9 doesn't play the wtv files with the HD content from Media Center.

Might have missed it but why are you trying to use a video card plugged into a pcie 1x slot? I wonder if it is a power issue ie it is not getting enough power though the 1x slot.

Bcos I only have a single PCIE-1 slot - it's not a x1 slot, it's a PCIE generation 1 slot - if that doesn't confuse the matter further!
I don't think it's a power issue - the card works fine in every regard except that it doesn't do hd decoding. It could be, I suppose... That'd be easy to change...
