    When watching Satellite i can somestimes notice what appear to be the scanning lines, it is less Pronounced whislt watching DVD's but is still sometimes there

    is there a way to cure this or do I have to accept it with sky and will progressive scan help when I change my Sony CX850?


    thanks

    Progressive scan will certainly help to give you a better picture but it sounds to me like you're picking up interference from somewhere.

    Are your interconnects running close to the mains cables? How is the Sky box connected?

    Thanks for the advice, but I really don't think it interference, its there depending on the type of scene, not all the time

    FYI

    Sky box scart to component output


    I am sure these are the lines that make up the picture, but I could be wrong


    thanks anyway

    Have you tried connecting Sky to the projector directly using Scart->S-Video ?

    I only use mine for watching DVDs so my TV's not even in the same room. I'm sure there's several others here that do use a Sony with Sky though.

    Good luck

    yes that was my original setup

    perhaps I am not explaining the effect correctly, in some scenes I get jagged edges which appear to be caused by the scanning lines.


    judging by the lack of posts perhaps all you other Sky to projector viewers have pixel perfect pictures =;-)

    thanks

    That's the result of an interlaced picture. Using a projector really shows up the deficiency of PAL and NTSC formats.... they're not designed to be displayed that big! Try an NTSC disk which can use the de-interlacer of the projector to see a real difference.

    You can get a progressive DVD player like the Arcam DV88+ but for Sky you would need an external de-interlacer to remove the effect... not sure how good the Pro-V is but it might be worth a look.

    Progressive DVD output really is significantly better. If you have Star Trek Insurrection, watch the first scene where the camera pans over the village - there are jagged lines everywhere and the roof tiles are just a blur.

    I got a ProV to try with my 10HT. Unfortunately since the ProV outputs VGA, the sony sees it as a PC signal and you can't get it into widescreen mode. Kind of negates the point of having a widescreen projector, so I sent it back!

    If you are seeing jagged lines on programming from Sky it's likely to be that the VPL11 is not so good at de-interlacing PAL film or video source material. Using an external de-interlacer may well help this.

    As Nigel says the unit is good with film sourced NTSC in the first place so you probably wont get any benefit from a progressive scan DVD player with NTSC material.

    Thanks

    what about progressive screen with PAL?

    would that be any better?


    Cheers

    Same thing applies although PAL progressive is done slightly differently. If you can get a PAL progressive DVD player then you will see the same benefits.

    Have a look at the progressivescan website at the top of the page, far right.
