I have a notebook using the GMA 4500MHD chipset graphics. I'm running Windows7 x64.
My current driver version is 22.214.171.1241.
According to the specs this chipset should have full support for accelerating MPEG-2, AVC and VC-1 coded movies.
Full support means:
MPEG-2: VLD + iDCT + MC
VC-1: VLD + iMDCT + MC + LF
AVC: VLD + iMDCT + MC + LF
This is true for MPEG-2 and AVC. But for VC-1 there seems to be no support for VLD.
Exactly the same SW-setup on another computer with an ATI graphics card supports
VLD for VC-1. Hence it can not be a problem of the media-player or the codec.
Question: is this a known problem of the driver or the chipset ?
addendum: restested on Acer Aspire 3810T. This notebook has a buildin GMA 4500MHD and an additional, switchable ATI Radeon 4330.
GMA 4500MHD: AVC ok, VC-1 no support for VLD
ATI: AVC ok, VC-1 ok
So either the specs for the GMA 4500MHD as listed in wikipedia are wrong or the driver is faulty.
