well i got an hvr2200 yesterday and after a bit of mucking around i've got it close to sorted.

1. Located in Chch, after trying mediaportal (scanning all new zealand regions, or just the christchurch options)
i don't pick up any TV3/C4. anyone know why this may be?

2. System i'm running is as follows:
Gigabyte P31-DS3L mobo
Intel DC 2180
2x1GB DDR2-800
8600GT HDMI Out
HVR2200

installed fresh install of Vista HP after mucking around in XP,
installed Vista SP1, all windows updates, required .net frameworks.
Installed latest nvidia driver from nvidia.com, and any other drivers needed.
Installed Cyberlink PowerDVD 8 Ultra. Loaded PowerDVD and ensured Hardware Acceleration was ticked.
Installed MediaPortal and set it up using TV Server as per cranznz's guide.
Using Powerdvd 8 Ultra deluxe H.264 codec for H264, all other settings the same as the guide.

Now all channels (minus TV3/C4) are detected, TV1-TV7 all run fine, (occasional jerkiness) however when I try
view the FreeView HD Channel the picture is very jerky.
CPU Usage is minimal (5-10%) from what i've seen.

Is there something i have missed, or anything I could try? Is it possible I just don't have a good enough
signal? have a UHF Aerial on the roof, TV Reception is fine.

Any help appreciated. Not toooo fussed on getting TV3/C4, but would like to be getting smooth performance on
the channels I do have.

When the TV-Server is scanning the frequencies for Christchurch does it scan the MediaWorks (TV3/C4) mux (698000)? If its not finding a signal on that freq it will tell you. Below are the freqs from page 1 of the sticky thread that started this forum.
Christchurch:

TVNZ 682000
TV ONE (720p Upscaled)
TV TWO (720p Upscaled)
TVNZ 6 (576i SD)
TVNZ 7 (576i SD)
TVNZ Sports extra (576i SD)

Mediaworks 698000
TV 3 (1080i)
C4 (576i SD)

Kordia 706000
Parliament Tv (576i SD)
Maori Tv 4:3 with 16:9 flags (576i SD)
3KSD
4KSD
5KSD
6KSD
Tv Central
Radio NZ Concert
Radio NZ National
Freeview | HD

If you are running MP RC1 or 2 then there is also a Christchurch Infil option in the list of tuning options. That may work if you can't see Sugarloaf. I am not completely familiar with the system down there but would have assumed all the freeview muxes would be broadcast from each location.

Check your CPU load to see if Hardware accel is working.
If you are using Vista, have you selected EVR as your Video Renderer Setting? (Mediaportal Config - DirectShow Filter Control - Video Renderer Settings and select Enhanced Video Renderer (EVR) button). That may help the smoothness. And make sure hardware acceleration is selected in PowerDVD AND MediaPortal (DirectShow Filter Control - PowerDVD Decoder Settings). Hope I'm not telling you how to suck eggs, but I don't have the guide up in front of me.

thanks for that,

enabled EVR within MP and TV2 etc. appears to be running smooth.

When i try load the Freeview HD i get a jittered noise but no picture, When i run the test channel i get a black screen no noise.

Scanned within Christchurch (both sugarloaf and infil) and get 'No Signal' for 698000.

anyone have any ideas?

It really sounds like a signal problem, Are you in a built-up area? what's you UHF antenna like, cable, diplexer, etc?

I notice your motherboard has the PCI-Ex1 slots quite close to the PCI-Ex16 slot for the graphics card. I had trouble with my hauppauge card when I put it in a slot too close to the graphics card (RF interference). Just an idea if all else fails.

As i've found by using a Freeview iDTV, the coax cable you use makes a big difference, if you can run higher quality RG6 to the card this may help signal instead of the thinner usual stuff.
