Jerky playback (1 Viewer)

I have an mkv file and it works fine on VCL on a 6 year old laptop but on MP on my PC the movie is jerky every now and then. I ma using the Divx codec for MKV files.

Hi Jay,

I, too, have problems playing back .mkv's on client machines. Poor playback can be caused by many different elements.

Can you give some more info.

What graphics card are you using and the driver version?
Which codec is being used to play the .mkv (press Shift & 1 during playback for a detailed info screen)?
Which operating system are you using?
Do you have any codec packs (SAF, LAV, Shark) installed?
Is your GPU doing the processing?

I started a thread about my poor playback HERE

I am on Windows 7 and the gfx is onbaord. It's a

GeForce 7025.​

I got the following for the play back info.​

DirectSound Device, Enhanced Video Render, MPC - MPA Decoder Filter, Divx H.264 decoder​

The only codecs I installed were Divx, ffdshow​

Hi Jay,

Sorry for delayed response.

If your playback is jerky I would suspect that the codec is not using the GPU for video processing. With the problems I have had I downloaded 'nVidia Inspector' >>here<< This enabled me to see what the GPU was doing when different video formats were being played back in MP. Obviously you would have to run nVidia Inspector and your problem video file on MP, at the same time, so you can see what Inspector is reporting - just don't run MP in fullscreen mode (Alt+Enter to switch modes). This helps to narrow down any codec/GPU problems as Inspector should show how much GPU processing power is being used - if it is zero, then the codec is not doing what it should do.
