@ray
once you enable the hardware acceleration, no need install coreavc.

have you try this??

@dlwl

Same here. Was using the integrated MPC that comes together in the Klite. But mine running good le.. Weird!

@Kabu

Yea. But if ur on Nvidia card, coreAVC is a need as we need the CUDA.

i think i sort of discovered the problem already. only that movie that i tried, the cpu usage goes to about 50%. tried with other clips like movie trailers, about 10% or less only. so it's the movie encoding perhaps?

btw, what about those with old gc, like geforce 5/6 series or ati 9k/x series? they don't have hardware acceleration right?

old gc dont have that feature, eg. 7 series. so have to fully depend on CPU to process.

btw, according to the link i provide, seems only radeon 3k/4k series.

"For graphics processing we need:

* nVidia series 8*, (9)xxx and GTX or newer.
* ATI Radeon HD series 3000 and 4000 or newer" -quote from guru3d

i wonder if ray's x2600xt can run or not.

2xxx series already have avivo build in already rite?
afaik even the previous series also have already...eg x1950
i see the chart in ati's website before..

my rig cant even play 720p with coreavc, haha dunno what im doing wrongly there

@kabukiawie, I'm not sure with that. Hardware acceleration with HD movie playback.I guess i have to PM him and ask for details.The link is showing that HD3xxx and above is able to support but i got other info from AMD website too.

@fylon,currently i'm with CoreAVC too. edmin has guided me how to force the mpc to use coreAVC codec. Previously my setting wasn't pointed at coreAVC.

@jcsy,I think you can force the software to use coreAVC codec to play HD movies. Did you set that?

@dlwl,
yes HD2xxx series has avivo but i have no idea how to use it.Lolz

@ray
no harm trying the method. last time even ed's also can play 1080p with his 7600 with coreavc. so if really cant apply that method, coreavc is the only way.

i set it but it wasnt runing in the lower right of the system tray

my media player classic , i have set it

but i think it is using ffdshow still, even after setting coreavc

do u think a reinstall will solve the problem?

@ray, one more possibility that your HD files not running smoothly maybe caused by the HD files is not encoded in H.264. If encoded in xvid, then your CPU will have a hard time keeping up with the processing. H.264 can be accelerated by GPU but not others.

i m very sure your configuration is not right. reinstalling coreavc will not help you at all as MPC is not loading coreavc in the first place.

ok maybe later ill take a screenie of my current configuration and what movie files im trying 2 play, and what are the results of configuration

maybe can understand more from there

I need to correct this statement is is pretty misleading. Coreavc is utilising CUDA to accelerate it's own decoding/computing engine, since it is not tapping into DXVA directly. if your MPC is configured to run DVXA acceleration (guide available @ guru3d), then the GPU power is already being harnessed to decode h.264

CoreAVC is not a must have when u have hardware acceleration. CoreAVC's function is to decrease CPU workload in decoding H.264 files when a hardware accelerator is not available. The worse thing about CoreAVC is....it's not free

@Ray, you can also achieve similar results. Dump your coreavc, just install latest Klite mega codec pack. following the guide on Guru3D, enable the DVXA acceleration. Coreavc is still computing on your CPU. Using DVXA, it will run entirely on GPU.

Guys,you can try MPC Home Cinema.I PMed the guy and he said he was using MPC Home Cinema. He said coreAVC isn't going to utilize the hardware acceleration.

but our hardwares, well mine at least, dont support computing movies from GPU leh

that dvxa will run meh ? old agp x800 i dun think so loh

bro, if u dump coreavc and use dvxa entirely, i can guarantee you seeing immediate drop in CPU usage. Unless you are using CoreAVC 1.9.5.0, that has the ability utilise CUDA on your 8800GT card (processing assisted by GPU from coreavc). Oh, make sure you have installed the latest driver with updated CUDA.

Then, CoreAVC is your only chance.

thats why i need u guys 2 help me harness the strength of 478 to play movies, lol

because at this point, i really given up and wan buy whole new system 2 watch these nasty mkv files
