Need help with 780G and h.264 playback

[mazeroth]

I purchased the following ASRock motherboard and a 7750 Athlon X2 black chip a few months ago for my HTPC hooked into my projector and it's not capable of 1080p playback with only the CPU working.

I've overclocked the chip to 3.4 ghz and while it does help when there's too much movement on the screen it will display artifacts for a while before clearing up. It has no trouble decoding 720p movies but the 1080p are giving it trouble. What I'm wondering is what do I need to do to get the 780G onboard to do the video decoding? I'm decent with computers but if you could dumb it down I'd appreciate it. Also, can I use both the VGA and DVI outs at the same time with two different monitors at different resolutions? I want to put an older 15" LCD with RGB input in my media closet so I can navigate the computer that way and play audio if I want to, without having to fire my projector up.

Thanks!

Wow, this is a bit of a surprise... I should think, even without graphics-hardware decoding, the Athlon X2 7750 should be able to play H264 video at 1080, even more so given your overclock. Somehow I suspect something else may be the issue...

That said, it depends on what your file format and codec are, how dense (bitrate) the H264 data is, and what software you're using. I don't think all H264 video is the same (I've never been quite able to figure this out) -- are you playing from Blu-ray, is this in fact an X264 file in an MKV container, etc? (God, I hate the chaotic state of 'computer' video...) Only certain media-playing apps are programmed to take advantage of graphics processors. The popular 'pay' dvd players (eg PowerDVD and WinDVD) can do this. VLC cannot.

What really matters is the decoding libraries used by the media playing app (or frontend). I believe, for instance, you can buy one of the above software packages, but then employ its hardware-assisted decoder in another media player app. Whereas FFmpeg libraries cannot take advantage of graphics processors and so apps derived from it (VLC, MPlayer, etc) won't as well.

Most punters seem to use Media Player Classic - Home Cinema. It has some support for graphics-hardware acceleration.

i havnt messed with this in awhile, but dont you need the avivo package installed to offload the processing onto the gpu?

I have a 780G mobo and no problem with 1080p.

try this:
Get the latest CAT drivers
Get a good H264 codec. I like the core avc software

Also try getting media player classic home cinema
http://mpc-hc.sourceforge.net/
it comes with it's own codecs and is free

I'm not sure about the second display thing.

You should have posted in Motherboard Forum.

To be on a serious side - What OS are you running on it? Codecs installed? Player of choice?

From my testing 780G + Kuma handled 1080p very well, except those outside the common specs.
