I've been a long time reader of Tom's hardware, but now I'm facing a problem I just can't seem to solve on my own, nor with existing posts..
Recently, I bought a nice 40" LCD TV (Samsung L40A 856). To be able to use it to the fullest, I decided to build a mediacenter/downloadcenter/server to use with it.
Here's the specs:
HTPC: ASUS P2-M3A3200 (HD3450 was installed, but I took it out, as it has an onboard HD3200 which does the job)
CPU: AMD ATHLON X2 5050E
RAM: CORSAIR 2X 1GB PC2-6400 TWIN2X2048-6400C4DHX (4-4-4-12)
HD: WD HDD 1TB 32MB GREEN
Bluray: LG GGC-H20LRB
A pretty typical low-budget mediacenter I'd say.
On that, I installed Windows Vista Enterprise edition, and installed all updates and service pack.
To be able to play all video formats, I installed the Combined Community Codec pack. (CCCP)
I'm using the latest ATI Catalyst control center (9.6).
The TV is connected to the onboard HDMI-out.
On to the problem!
One of the things I want it to do, is play video - Xvid, DVD, 720p, 1080p and the bluray disks.
Up to 720p, everything runs like a charm, although I'm noticing an 80% (!!) cpu load on 720p.
If I'm not mistaken, the ATI avivo chipset should do most of the computing, taking nearly all the load off the CPU.
When I try to run 1080p, the video plays at around 50% of the normal speed, and a lot of frames are dropped. Audio runs out of sync etc. Turns out my CPU is 100% used!
I've done some research and found out it might have to do with codecs. Thus, I tried a powerdvd 7 codec (HD compatible). Although it ran a little better, it was still no good.
The question: How on earth can I make this work!?
Subquestions: Am I doing something wrong? Can't this system run HD?
Thank you in advance for taking the time to read this and perhaps even help me!
Yes, I have. It doesn't make any difference. I tried that using the DVI to HDMI converter which came with my desktop's HD4890. There wasn't one included with the HTPC (which kind-of tells me that we're supposed to use the onboard HDMI..).
Also, I prefer to keep it out, to lower the power consumption (11w, without the hd3450 it sucks ~50w). The pc doubles as download center for my fibre internet.
Yes, I have. One of the first problems I ran into was that the HDMI didn't output anything. After a lot of tinkering, it turned out I had a feature disabled in the BIOS.
After that, I checked everything the BIOS had to offer and enabled it all.
I've also installed ATI's Cool'n quiet application - but it doesn't seem to do anything. A strange app it is. It just gives me a monitor. The CPU fan always makes a noise, even when it's not hot. That's another issue though. Is it related to the AVIVO chipset?
EDIT: Thanks for the replies by the way, gonna sleep now (1:20 AM here!), will check back tomorrow!
Have you possibly tried Omega drievrs? They are third party enhanced ATI and nVidia drives but supposively are pretty good. A friend of mine has a old AGP system and they ahd support with the newest drivers for AGP in them.
I came across the exact same problem in decembre 2009 with a Dell Zino PC.
It has a very weak single core AMD CPU but a good ATI Mobility Radeon 4330 GPU, so it should be able to decode HD .mkv using the GPU and the Avivo drivers.
It took me 2 days roaming the web to find the solution : Media Filters Pack 4.0.
Before that filter pack I tried all sort of settings using both Shark007 and CCCP codec pack, trying to activate GPU hardware decoding, but it has been a miserable failure.
Media Filters Pack 4.0 has an option "hardware accelaration" when you install it, that you have to check. the coolest thing is that you can read HD .mkv in Media Center, you don't have to use another player like MPC.
