    Hello chaps,

    Just a quick one. When using the HCPC for DVD playback it appears that when there is some movement on screen the previous frame is still visible on screen thus causing slightly blurred images. What causes this and what can I do to fix it?

    My PC is a 3.0Ghz @ 3.45 and using Sonic Decoders in ZP. I have tried TT but it exhibits the same trait.

    Cheers,

    Ajax.

    Are you playing NTSC or PAL?

    Are you using CRT or LCD or DLP or Plasma?

    Hello,

    PAL and NTSC on a Panny AE500. It also does it on my monitor. I have the Panny set to 750p/50hz but it did it at 750p/60hz also. There are so many different terms I dont know if its Judder, poor delinterlacing, 3:2 pulldown etc. It's not too annoying but it can be at times. It doesnt do this when my Sony DVD player is connected to the PJ via scart.

    When people move across the screen it they start to blur slightly as if the previous frames are still there. This happens even if somebody moves slowly across the screen and even worse with fast movement.

    Cheers in advance,

    Ajax.

    Sonic and TT use the same filters. Try PowerDVD or WindDVD just as part of the elimination process.

    What GFX card are you using?

    Hello,

    I am using a Sapphire 9600XT 256mb. I have used PDVD and WMP9 and it still exhibits the same thing.

    I'm a bit lost really.

    Well your Panny is an LCD and all LCDs suffer from motion blur to a degree - it doesn't sound like that.

    PASS.

    It's defo not the Panny as it occurs on my Monitor as well. Should DVD playback behave exactly the same as DVD playback on a STB?

    More or less.

    A STB has one clock to work from dor audio & video sync.

    Your PC is using a clock for the audio that isnt running in sync with the clock for the video. So the issue that HCPCs are prone to is stutter as the software tries to find a constant balance between the two. This can be virtually illiminated.

    But it doesn't sound like what you are experiencing.
