1080P video files skip/freeze on GTX260?

I'm running this hardware at 1920*1200 on windows xp SP3:

MoBo: Evga Nvidia nForce 680i
CPU: Intel Core 2 Duo E6700 @ 2.66Ghz
GFX: Evga GTX 260 Core 216 896MB
RAM: OCZ 2x2GB DDR2 1066 [PC2 8500]
PSU: SilverStone ST75F 750W [4x +12V@ 18A each]
HD: Samsung 500GB 7200RPM SATA HD
Monitor: Dell 2407WFP-HC 24-inch @ 1920*1200

I'm having problems playing back 1080P video using VLC media player with a .mkv file. I can play 720P fine, however 1080P seems to skip slightly or pixelate at different parts of the file, like every 10 to 20 minutes it skips or pixelates or freezes for a few seconds. Other wise it plays fine.

I'm wondering if its that VLC isnt the best player to play back more intensive 1080P video files? Are there any other players that can play .mkv files any better?

Or could it be my PC hardware? I know its getting older, but is possible that the [Core 2 Duo E6700 @ 2.66Ghz] is just too slow to smoothly play back 1080P videos? I have tried multiple .mkv files, and VLC seems to struggle to play them about the same, with some freezes and skips, although it still plays the majority of the file ok.

Please note, if your video is 1080p mkv/h264 file, it will not benefit from hardware decoding on video cards unless you are using CoreAVC. Hardware decoding usually only benefits from software such as Arcsoft HomeTheatre/Cyberlink PowerDVD on blu-ray if one does not install CoreAVC filter. So you're most likely trying to playback 1080p all based on your cpu.

I would say, install Media Player Classic Hometheater edition + CoreAVC and you shouldn't have to upgrade your cpu.

CoreAVC does not use the GPU to accelerate decoding. It's just a very efficient software decoder (entirely CPU).

Like nismotigerwvu said, MPC HC using DXVA is the way to go, as this will offload the work to your GPU.

Yes it does.

Still, you don't need CoreAVC to get hardware decoding of (compliant) H.264 and VC-1 video streams.

Media Player Classic HC has everything you need built-in.

If you have a quad-core processor, I'd just use ffdshow-tryouts, and enable the ffmpeg-mt H.264 decoder.

The reason your video skips in VLC is that VLC only has the standard libavcodec, which can't effectively multi-thread. Decoding 1080p H.264 definitely requires more than one core, so you fail :) ffmpeg-mt is fully multithreaded up to 8+ cores, and will rip through decoding easily.

DivX's new free H.264 decoder is even faster on a modern CPU - a little diamond in the rough as the saying goes :)

The advantage of using software decoding is that you can post-process the video - i.e. use software upscaling / grain addition. Hardware acceleration forces you to directly connect the video decoder with the video renderer, since it all happens on the GPU.

thanks for all the ideas, I got the K-Lite Codec Pack, and using just normal windows media player it now plays all my 1080P files perfectly.

Yech..

K-Lite... :p

Try out media player classic HC... without K-Lite installed. All you need is haali media splitter and ffdshow-tryouts.
