sbiddle:smbunn: I am getting a ATI Radeon 2400 HD AGP card. $115 will be well spent if it works, which according to the specifications it should do. A few US reviews of it decoding H.264 said it was identical in speed to the HD 3850 and twice as fast as the Nvidia 8800GTS. It also said the noise reduction and de-interlacing were far superior to Nvidia.
I will let you know if this card does the trick.
You're wasting your money.
ATI chipsets have known reported issues with DVB-T in New Zealand when it comes to decoding interlaced H.264 video and I've personally verifed the issues with 2400, 2600 and 3850 video cards in several different systems.
There also appear to be issues with hardware acceleration of H.264 content using AGP with varying reports on whether this does work succesfully or not.

mattie47: I'm pretty sure i've read every ones post and hopefully what i'm asking hasn't already been asked :-) I'm being offered an insane deal from a friend for a bunch of computer stuff. Any how hes offering me the Sapphire HD2900XT 512MB PCI-E as part of the deal. I'm pretty sure it does h.264 decoding as on this page: http://www.cpu3d.com/content/view/1742/53/1/1/ it says "Integrated HD audio controller with multi-channel (5.1) AC3 support"..."Integrated AMD Xilleon™ HDTV encoder, Provides high quality analog TV output (component/S-video/composite), Supports SDTV and HDTV resolutions"..."HD decode for H.264/AVC, VC-1, DivX and MPEG-2 video formats, Flawless DVD, HD DVD, and Blu-ray™ playback"..."HD video processing"..."MPEG-2, MPEG-4, DivX, WMV9, VC-1, and H.264/AVC encoding and transcoding" It should work with freeview NZ alright shouldn't it? After I've bought that all I'd need is a cheap USB DVB-T tuner without Hardware encoding wouldn't I?
ajst2duk: I think I've found the perfect HTPC card - gigabyte o/c & silent heat pipe 9600GT, I'll poost a report sometime in the weekend.
askelon: nVidia has 3 generations of H.264 hardware acceleration. The 7x00 series, 8800GTS/X are all Gen 1. It doesnt support Freeview hardware playback. Gen 2 was the earlier 8x00 cards which support playback with no problems, Gen 3 is the current equipment which should include all the newer 8x00 cards and the 9x00 cards.
Gen 1 will more or less require decoding via the CPU (approx 30-40% CPU Usage), Gen 2 & 3 are decoded via the graphics cards (approx 3-5% CPU Usage).
Cards that will work with no problems are as follows:
8400GS (not suitable for games though)
8800GT (not GTS/GTX)

Am finding this thread a little depressing as it took me a while to get good output from my GA-MA78GM-S2H motherboard with its integrated HD3200 only to find that channel-changing sometimes caused problems. I have been putting that down to poor reception/USB DVB-T stick but there's obviously more to it than that!
Last night I started a re-install of everything from the ground up as I'd installed numerous ATI drivers, virus software and MediaPortal SVNs before getting good pictures on all DVB-T channels.
I will be a bit more methodical by ghosting the base OS (XP) and trying various Catalyst drivers, MediaPortal/GB-PVR in turn. Will let you know what I find.
Note that Catalyst 8.4 has recently come out so fingers crossed that ATi have pulled finger or it's another trip to the shop!
ajst2duk: I tried the latest catalyst, I didn't want to give up without a fight !!!!

Oh god. Another $279. Luckily the Mrs doesn't read the forums. I wonder how smbunn is getting on....?
It's so friggin annoying. Like most things technical in my house, it seems to work until I show the wife!
