As implimented by Gigabyte , GA-EG45M-DS2H
While the specs says it decodes H.264 the reailty not quite here.

PowerDVD even says it supports it.

I could not easily get it working on xp or vista.

This poster had more success.

i can't get mine gma4500hd on g45 chipset to work on freeview hd. playing h.264 mkv files the 2 cores use 50-100%. it does support 1080@60fps though, but my samsung full hd plasma can't see the output (a known samsung tv issue).

I' ve had this board for a few months, and emailed gigabyte about the limited video acceleration with no effective solution.
Desite Intel billing it as the ultimate home theatre motherboard. 
Intel has had made the G45's  (GM4500HD) DXVA not very usefull in their drivers at all.

-No DXVA at all in XP at all.
-Propriety Intel DXVA2 guids only in Vista, ie intel did not follow the microsoft standard for DXVA that could be used by all codec providers.
 As far as I know only Cyberlink, Arcsoft and maybe Correl winDVD can get DXVA(2) going, as they signed up with intel to get the info required.

Wish I knew all this before I bought it, maybe it can some one else.

info sources

quote "As an OEM and a channel program partner I have open a support case.
It's now closed with this response: It's confirmed INTEL doesn't and won't support G45 HW Acceleration (of any type) on Windows XP."

you won't believe it.

played 1080i tv3 feed from fossie perfectly on powerdvd 8 with average of 15% on both cores of my 2.0GHz cpu ... max was 20% on both cores.

so it DOES do hardware decoding .... must be a dvbviewer issue as i was using an older version.

yay some hope :) just find the right 3rd party software!
