Reading the forum topic below seemed like a round-a-bout way of doing it.

Here is the easy way. You need a GFX card capable of it, eg. nVidia Purevideo.

Vista:

Ensure you have your cl264dec.ax registered.

(if you don't have CL264dec.ax, just download it for free Cyberlink PowerDVD Trial Version has it)

In DVBViewer when playing DigitalTV, goto Options and ensure Vista Enhanced Video Renderer is selected as Video Renderer (under Hardware). Also select the H264 PDVD codec as the H264 decoder.

When video is playing. -> Options at the top -> Filters -> PDVD H264 Filter -> Tick the DxVA box and rebuild the graph (or restart DVB viewer).

In XP:

Do the same, except make sure you have .Net 3.0 framework installed and the EVR.dll and DxVA2.dll registered.

Hi, I've just installed the .Net 3.0 framework. How do I register the EVR.dll and DxVA2.dll?

Start > Run > regsvr32 path/to/EVR.dll
Start > Run > regsvr32 path/to/DxVA2.dll
Obviously make sure they are in a permanent place when you register them so they arent moved.

Can somebody confirm h/w acceleration will work under XP if you use the .net 3.0 EVR? It's certainly not supposed to work and I never managed to get it going. It will work fine however under VMR9

Thanks very much!
I registered evr.dll no problem, but when registering the dxva2.dll I get the message "dxva2.dll was loaded, but the DllRegisterServer entry point was not found. This file can not be registered."

Ok, even though I still can't get the dxva2.dll registered, I can now use EVR in dvbviewer ikn Windows XP. Unfortunately it freezes up whenever I use it with H.264 PDVD8.
But do get a picture with CoreAVC Video Decoder at 50fps! A huge improvement over my previous results with PDVD8 and VMR9 at 20fps.
Unfortunately, the audio is out of sync with CoreAVC and the CPU is at max with both options, but then I am running an old single core 2.6ghz.

I had similair results on several installs. 

EVR introduced DVXA2 for h/w acceleration under Vista and has legacy DXVA support. In Vista it does not support h/w acceleration using this DXVA fallback which is why you will not get h/w acceleration working using VMR under Vista and need to use EVR.
 
It also means that under XP you cannot use EVR for h/w acceleration, you need to use VMR. EVR is very much a hack under XP and is not officially supported.

Ok. How do I get h/w accel using VMR then? I'm using PDVD8, NVidia PureVideo Plugin installed, Dxva checked under PDVD8 filters, but I'm still getting only 20fps and 100% cpu usage

I hate being the bearer of bad news but that is your problem. You need a PCIe board with a minimum of a 8500GT card. The 4200 is an ancient card!

Ah I had a bad feeling about this!
Thanks for your help guys, looks like I'll have to splurge on some new hardware after all. Cheers!
