Did you actually get it to play HD (1080P video) at decent framerates? Did you plug into an HDTV and actually watch something, or did you just play HD on the tiny netbook's screen?

Also, this should work on a 1101HA since it uses the same chipset and processor right?

Do you have 1 or 2 gigs of ram?

Is there any way to do this on Windows XP that you know of?

Media foundation isn't available for XP, so you can't use the Intel VC-1 codec (WMV-HD)

But you can use MPC-HC with Cyberlink H.264 codec like it's describe on the third party software part of the tuto. To use Cyberlink H.264 codec in WMP11 (which support DXVA2), i need to find the CLSID in XP registry but i havn't any PC under XP but with help of someone with an xp installation, it's possible.

So where do you get all these decoders? for example the Cyberlink decoder, where do you get and how to install it?

One issue there seem to exist no fully legal way to accomplish this. Picking up pirated drivers from odd sites makes things work (thanks for sharing the details!) but I would like players such as Asus to distinguish the described recipe, arrange legal licensing negotiation with the decoder vendors and provide this support that make the GMA500 fly. Or maybe Intel is the more appropriate player to do this since their chipset is used by several netbook vendors. In fact given Asus/Intel and others know the potential of the hw it's a mystery they release machines with it without making sure the capability is exploited to its fullest.

You could use default WMP codec with DXVA or Intel H.264/AVC codec for H.264/AVC files and Intel VC-1 codec to play WMV-HD, it's fully legal. Intel is working on the GMA 500 driver as the latest release was only a production version, surely final driver will be released when Windows 7 will be out.

When I then tried trying to use MPC-HC on the demo clips I get the following error messgae when I try to open them:
“No D3DX9 dll found. To enable stats, shaders and complex resizers, please make sure to install the latest DirectX End-User Runtime”

Thanks madden187, i forget to say that you need to update DirectX 9 runtime, first post has been updated.

for the MPCVideodec codec you need to install first MPC-HC.

At this stage I received the following error message:
"The module “mpcvideodec.ax” was loaded but the call to DllRegisterServer failed with error code 0x80070005"

I was then unable to find MPCVideoDec in the list when I opened MPC-HC.

Yes because MPCVideodec hasn't been registered. try to reinstall MPC-HC and register again the codec

However, after clearing this  - the clips did play as follows:

1.    Robotica played but with the sound lagging behind in spurts.

2.    Hancock trailer played better with only very slight frame judder.

I havn't this problems but:
-Robitica is a WMV-HD, so you need to use WMP to play it.
-take care to windows gadgets, if the player (WMP or other) touch them, videos will lag.
-deactive aero
-On all files, the very first frames will be dropped, it's like that.

Plusi,

some comments (even if they are rather late, sorry... :-)

First, a general comment: possibly it would be useful to review/re-check the processor usage values displayed by DXVA checker. I doubt that the values displayed would be real, because chekcing the processor usage of MPC-HC during playback does NOT show any significant difference when using different CODECs ... or at least I could not see it. Also, theoretically there should be minimal processor usage for all DXVA compatible decoders playing the same movie (only separating the streams and sound decoding is done by the CPU, which is easy even for the Z520 Atom), but video decoding (which, on the other hand requires a HUGE amount of calculations) is done by the GMA 500. So, theoretically there should be minimal difference between any DXVA codecs, ALL should play back video with practically zero CPU usage ... and Task Manager seems to support this theory. For this reason, I did not install the PowerDVD codec for H.264 playback in MPC-HC (in Windows 7), just use the built-in decoder of MPC-HC (but playback of VC-1 does require the Intel CODEC and using Windows Media Player).

So, if there is a problem with the playback of a h.264 movie, then you can right click on the image surface to display the popup menu (useful to pause playback before doing it, so it is faster) and from the popup menu, choose Filters/MPC Video Decoder.

Now there are two options:

1. If, in the lower part of the Properties window (within the DXVA settings area) you see DXVA Mode as "H.264 bitstream decoder, no FGT" or something similar, then the video is played back with DXVA and it should work well, run without dropping frames supposing you disabled Aero, and use the latest video drivers and directX. Processor utilization in this case should be under 50% during playback.

2. On the other hand, if you see the DXVA mode as "Not using DXVA" than the CPU is decoding the movie and it should be much slower. In this case possibly the movie itself is not compatible with DXVA decoding (some of the encoding parameters were set outside the limits allowed by hardware decoding when the movie was compressed). In this case there is not much chance to playback the movie on the GMA 500 ... so, you should get another version of the movie with right encoding settings.

Also, when using DXVA, MPC-HC displays on the status bar the "Playing (DXVA)" instead of simply "Playing" but this does not seem to be a reliable indicator for me (sometimes display false info), so, I use the above method if I want to be sure.

Also, DXVA decoding requires NO ADDITIONAL FILTERS between the player program and the DXVA decoder. E.g. if you use a third party program to display subtitles (like directvobsub), then you can forget DXVA. The ONLY way to display subtitles with DXVA decoding (within MPC-HC) is to use the built-in subtitle engine of MPC-HC and also you have to use the "EVR Custom Pres" renderer in order to successfully display subtitles.

By the way, I am only a guest from the 1101Ha group, because I only have a 1101Ha, NOT a T91, but they use the same processor/chipset, so, they are very close to being identical in this respect. On the 1101Ha, if you play back an 1080p movie with subtitles on full screen, then some frames are dropped (supposing you do not overclock the CPU using SHE). To get rid of this problem, you should use "D3D Fullscreen Mode", but NOT (!!!!) D3D Fullscreen GUI Support (for me, it causes dropped frames to return!!!). In D3D Fullscreen mode you have to use keyboard keys to change language/subtitles, but this way I can playback 1080p nicely (with subtitles on fullscreen) at 1333MHz core clock.

If you overclock the machine (+30% = 1740MHz) then full screen 1080p with subtitles works without the D3D Fullscreen Mode, so you can again use the GUI of MPC-HC but the machine uses more electric power (because of overclocking), so, if you do not have an AC outlet available around you, then possibly it is still better to use normal clock speed and D3D Fullscreen (especially if you watch a movie from the beginning to the end, in this case the missing GUI is not a real problem ... but it is really annoying for viewing short clips).

So, Plusi, I would try to:

- remove all codec packs from my machine (MPC-HC has everyting built in that you need in practice)
- would install the software accoring to faman's description (except I would use the built-in h.264 decoder of MPC-HC ... just because it is built in by default and works well)
- would check the movie whether or not it is DXVA compatible (I guess it is not, but MPC-HC will tell it exactly)

Have luck!

Very strange: Robotica is playing fast and smoothly in KMPlayer with MHC codec - and very slow in WMP12 (with checkbox DxVA turn on).

But I'm Legent on the contrary is playing very well in WMP12 and very poor in KMPlayer (I've tried all codecs: windows, MHC, Cyberlink, CoreAVC) - and I can't do better.

bump + test file

This is MKV sample from with VC-1 encoding... i am unable to play it although wmv VC-1 plays fine.

http://rapidshare.com/files/95088346/Pl … sample.mkv

pls test it on your setup and help me config my wmp/mpc to invoke same filters during MKV vc-1 playback that it uses during wmv.

PS:
Robotica works fine.
I am Legend works fine.

WMV: VC-1, H264 - works.
MKV: only H264 works, VC-1 doesnt work.
