    PC hooked up to my Panasonic AE500, I run dvd's at 1280x720 native resolution using PowerDVD.

    Most of the time it looks fine however when the camera pans slowly there is a lot of flicker.

    I assume its something to do with refresh rate, most of the DVD's I'm watching are PAL so 50Hz and I think standard monitor refresh rate is 60Hz?

    I tried changing the refresh rate in Powerstrip but I kept going out of the projectors range and sending the screen blank.

    Does anyone have a similar setup who could shed some light on what settings I should use to eliminate this problem.

    Thanks

    Are you running through vga or dvi, what graphic card are you using and what dvd software are you using. I have an ae500 and dont get any flickering on pans. When you say flickering do you mean juddering or jerkiness.

    I'm using DVI, graphics card is a XFX Ti4200 sofrware is PowerDVD

    Its definitely a flicker I'm getting, its only on slow pans, just a sort of flicker along the middle of the screen as if its not quite keeping up with itself.

    Is this tearing? A Ti4200 isn't sluggish I'd have thought. While playing PAL at 60hz can cause a stuttering, I'd not have thought your description was of that. In any case, my projector only accepts 60hz too and I don't see this sort of effect.

    What does playback look like on your monitor? What about VGA?

    Never noticed any problems with VGA though I haven't watched many DVD's through that.

    It's not down to a weak graphics card, I've watched stacks of the windows high def demos on here and they work perfectly.

    If its tearing (which it sounds like it is) it could be a video to audio sync issue. I couldn't get PowerDVD to work properly at 50Hz.

    Reclock has a very useful utility to show if the audio\video sync is an issue. I think its a tickbox at the bottom that shows vsync tearing. It will scroll a bar horizontally across the screen to show you if sync is an issue. You can then adjust your powerstrip settings accordingly to set this right.

    I dont think reclock works with PowerDVD though.

    Try a different software player to see if the issue persists.
