I use PowerDVD to playback DVD soundtracks on my laptop (Sony Viao FX-505).

I listen through headphones to get the Dolby Headphone surround sound effect.

The picure is fine but the sound is very "jittery".


What is the likely cause?

Is it Software conflict? I uninstalled WinDVD and Actua Player DVD playback software. No improvement!


I read somewhere that messing about with sound filters may help. Can anyone explain this to me in simple language?


Is it just that laptops have crummy souncards?

Would an Echo Indigo PC slot soundcard help? ( http://www.echoindigo.com )


Elcectrical noise?


Any (simple) ideas for a fix?

Much of the discussion on a related thread is above my head!


Thanks

I assume that you have no other software running, and no network card installed.


Is the sound jittery using WinDVD?


It may help to try using WaveOut instead of Directsound output (or vice versa). This will be an advanced option in the DVD software - e.g. to access it in WinDVD you need to download the separate WinDVD Tweaker software.

Hi Inti,

Thanks for your comments.

At the time of DVD playback, no other software is running. Virus checking is disabled.

I do have a network card fitted but I am never connected to any network or internet at time of DVD playback.


Jitter was worse in WinDVD. So I deleted it, perhaps foolishly!


PowerDVD does not give me access to the Waveout/directsound tweaks you suggest.
